Gel electrophoresis is a technique used to separate DNA fragments by size. DNA is cut by restriction enzymes into different sized pieces, which are then loaded into an agarose gel. An electric current is applied, causing the negatively charged DNA fragments to migrate through the gel at different rates according to their size. Smaller fragments travel farther than larger ones. After running the gel, DNA bands can be visualized under UV light and the sizes of fragments determined by comparison to a DNA ladder of known sizes.

Gel electrophoresis is a technique used to separate DNA fragments by size. An electric current is applied to DNA samples loaded into wells in an agarose gel submerged in buffer solution. Smaller DNA fragments migrate farther through the gel towards the positive electrode due to their higher mobility. After running the gel, DNA bands can be visualized under UV light and compared to a DNA ladder to determine fragment sizes. This allows researchers to analyze restriction enzyme digests of DNA and recover specific DNA fragments.
Electrophoresis 1
Gel electrophoresis is a technique used to separate charged particles like DNA fragments by size. An electric current is applied to a gel, causing negatively charged DNA fragments to migrate towards the positive electrode. Smaller fragments travel further than larger ones. DNA is first digested with restriction enzymes to generate fragments of different lengths. The DNA fragments are then loaded into wells in an agarose or acrylamide gel submerged in buffer solution. As an electric current is applied, the fragments separate by size. After completion, the gel can be stained with dye and visualized under UV light to see the separated DNA bands. This allows analysis and recovery of specific DNA fragments.

It works by applying an electric current to move the molecules through a gel or medium. Smaller molecules move faster through the pores in the gel than larger molecules, allowing separation. There are different types of electrophoresis that use different gel materials like agarose or polyacrylamide gels and techniques like pulsed field gel electrophoresis to separate different sized molecules. Electrophoresis is widely used in areas like molecular biology, genetics, and clinical testing.

Agarose gel electrophoresis
Agarose gel electrophoresis is a technique used to separate DNA fragments by size. DNA samples are loaded into wells in an agarose gel and an electric current is applied, causing the fragments to migrate through the gel at rates dependent on their size. Smaller fragments travel farther than larger fragments, allowing DNA samples to be separated into bands of distinct sizes that can be visualized after staining.

It moves through two common media - agarose gel and polyacrylamide gel. Agarose gel is used for larger molecules while polyacrylamide gel provides better resolution for smaller molecules. The document explains the principles, factors affecting separation, different types like agarose gel electrophoresis and polyacrylamide gel electrophoresis. It also discusses the requirements, steps involved and applications of agarose and polyacrylamide gel electrophoresis.
Gel electrophoresis
Gel electrophoresis is a technique used to separate molecules like DNA, RNA, and proteins based on their size and charge. It works by applying an electric current to move the molecules through a gel, allowing smaller molecules to travel farther than larger ones. Different types of gels like agarose and polyacrylamide can be used depending on the size of molecules being separated. Visualizing techniques use dyes to make the separated molecules visible. Gel electrophoresis has applications in DNA fingerprinting, analyzing PCR results, and DNA profiling for taxonomy.
Gel Electrohoresis
Gel electrophoresis is a technique used to separate DNA, RNA, and proteins based on their size and charge. During gel electrophoresis, a current is applied to move the molecules through a gel, with smaller molecules moving faster through the pores in the gel. This allows researchers to determine the size of unknown molecules by comparing their migration to molecules of known sizes. Key aspects of gel electrophoresis include preparing an agarose or polyacrylamide gel, loading samples and a ladder, running the current, and visualizing the separated molecules using dyes like ethidium bromide under ultraviolet light.

Gel electrophoresis.pptx
Gel electrophoresis is a method to separate molecules like DNA, RNA, or proteins based on their size and charge. It works by placing the molecules in an agarose or polyacrylamide gel and applying an electric current, causing the molecules to migrate through the gel at different rates depending on their size and charge. Smaller and more highly charged molecules move faster. This allows separation of molecules that differ in size by as little as a single nucleotide or amino acid. Common applications include analyzing DNA fragments after enzymatic digestion or PCR, separating proteins by molecular weight, and determining purity of samples.

Free amoebae
1) Amoebae are single-celled organisms that can change shape by extending and retracting pseudopods. They are found across eukaryotic life and include pathogens.
2) Well-known pathogenic amoebae that can infect humans include Naegleria fowleri which causes meningoencephalitis, Entamoeba histolytica which causes dysentery, and Acanthamoeba which can cause keratitis or granulomatous amoebic encephalitis.
3) Amoebae move using pseudopods, feed through phagocytosis or pinocytosis, and can form protective cysts. Their life cycles and pathogenesis depend
Enteric fever
Typhoid fever is a bacterial infection caused by Salmonella Typhi that spreads through contaminated food or water. It has varied symptoms over 4 stages including sustained high fever, abdominal pain, and delirium. Diagnosis involves blood or stool cultures and the Widal test. Treatment is with antibiotics like fluoroquinolones or cephalosporins. Prevention relies on sanitation, hygiene, and typhoid vaccines. Multidrug resistance is a growing problem requiring alternative treatments.
Filariasis
Filariasis is caused by thread-like parasitic roundworms that are spread by mosquitoes and black flies. The worms live in the lymphatic system and other parts of the body, and the females release microfilariae that circulate in the bloodstream. Over time, this can lead to elephantiasis with thickening of the skin. Diagnosis involves examining blood slides for microfilariae at specific times of day. Treatment includes medications that kill the microfilariae like diethylcarbamazine, ivermectin, and doxycycline. Controlling mosquitoes is also important for preventing the spread of filarial parasites.
Swine Flu
- Swine influenza, or swine flu, is caused by influenza viruses that normally infect pigs. It can sometimes be transmitted from pigs to humans.
- Symptoms in humans are similar to regular flu symptoms like fever, cough, and sore throat. It spreads when people with the virus cough or sneeze.
- Treatment involves antiviral drugs, which work best if started within two days of symptoms. Vaccines are also available to prevent swine flu.
Ebola virus
The document provides information on Ebola virus, including:
1. Ebola virus is classified in the genus Ebolavirus and family Filoviridae. There are 5 species that cause disease in humans, with Zaire ebolavirus having the highest fatality rate of up to 90%.
2. Ebola virus disease symptoms start suddenly and include fever, muscle pain, and headaches. Later symptoms include vomiting, diarrhea, and internal/external bleeding.
3. The virus is transmitted through contact with infected body fluids and tissue. Bats are believed to be the natural reservoir of the virus. There is no approved vaccine or treatment, though supportive care can increase survival.
Free radicles
Free radicals are molecules with unpaired electrons that are highly reactive. They are generated through oxidative metabolism and reactions involving oxygen. Common free radicals include superoxide, hydroxyl radicals, and lipid peroxyl radicals. While free radicals can cause damage to tissues, the body has antioxidant defenses like superoxide dismutase, catalase, glutathione peroxidase, and vitamins C and E that help neutralize free radicals. Antioxidants protect cells from the harmful effects of free radical formation and oxidative stress.
Eukar transcription
Gene expression in eukaryotes involves transcription of DNA in the nucleus, followed by RNA processing and transport of mRNA to the cytoplasm for translation. Eukaryotic genes contain both coding exons and non-coding introns. During transcription, RNA polymerase II binds promoters and transcription factors to initiate transcription. The primary transcript undergoes splicing to remove introns and join exons, producing mature mRNA for translation into protein.
Gene Expression in Eukaryotes
Gene expression in eukaryotes involves transcription of DNA in the nucleus, processing and export of mRNA, and translation of mRNA on ribosomes in the cytoplasm. Eukaryotic genes contain both coding exons and non-coding introns; the exons must be spliced together to form mRNA before translation. Three RNA polymerases transcribe different types of RNA in the nucleus, with RNA polymerase II responsible for mRNA and some small nuclear RNAs. Precise binding of transcription factors to promoter elements upstream of genes is required for transcription initiation by RNA polymerase II.
ELECTRON TRANSPORT AND OXIDATIVE PHOSPHORYLATION
The document summarizes electron transport and oxidative phosphorylation. It describes how electrons from NADH and FADH2 are transported via carriers in the mitochondrial electron transport system to oxygen, with energy released used to synthesize ATP. Protons are pumped from the mitochondrial matrix to the intermembrane space, building a proton gradient that drives ATP synthesis by ATP synthase as protons flow back into the matrix. This chemiosmotic coupling allows efficient conversion of electron potential energy to chemical energy in the form of ATP.
ELISA
The document discusses the enzyme-linked immunosorbent assay (ELISA), a biochemical technique used to detect antibodies, antigens, or other molecules in a liquid sample. ELISA uses antibodies and color changing enzymes to identify target molecules. It is a sensitive, quantitative, and widely used technique in medicine and research. There are different types of ELISA including competitive, sandwich, and indirect methods depending on the target molecule being detected.
Energy Balance
Energy balance occurs when energy intake from food matches energy expenditure by the body. Energy expenditure consists of basal metabolic rate (BMR), the energy required for basic body functions, thermic effect of activity and food, and adaptive thermogenesis. BMR accounts for 50-75% of total energy expenditure and can be estimated using formulas factoring in weight, height, age, and gender. Tracking energy intake and expenditure helps determine if a person has a surplus, deficit, or balance of calories.
Ethyl Glucuronide
Ethyl glucuronide (EtG) is a biomarker for detecting alcohol consumption between 1 day and 1 week. It is formed by conjugating ethanol with glucuronic acid in the liver. EtG can be measured in urine, blood, and hair samples and remains detectable for up to 90 hours after heavy drinking. Studies have found EtG to be a sensitive and specific marker of recent alcohol intake that helps address the need for a biomarker in the timeframe not covered by other alcohol markers. Liquid chromatography-mass spectrometry is commonly used to precisely measure EtG levels in various samples.
Electrophoresis
This document discusses electrophoresis, which separates charged compounds using an electric field. It moves negatively charged proteins in serum towards the anode at pH 8.6. Applications include separating serum proteins, lipoproteins, hemoglobin variants, and isoenzymes. Zone electrophoresis is commonly used and involves applying samples to a support medium like paper, cellulose acetate, or polyacrylamide gel. After separation, proteins are visualized through staining and quantified using densitometry. Serum protein electrophoresis is used to analyze the albumin and globulin percentages. Abnormal patterns can indicate conditions like multiple myeloma or liver cirrhosis.
Ecosinoid metabolism
This document discusses the metabolism of unsaturated fatty acids and eicosanoids. It notes that animals have limited ability to desaturate fatty acids and require certain polyunsaturated fatty acids from plants. These essential fatty acids give rise to eicosanoic acids that produce eicosanoids like prostaglandins and leukotrienes. The metabolism of unsaturated fatty acids involves desaturase and elongase enzyme systems. Deficiencies in essential fatty acids can cause growth and reproductive issues in rats.
Cytokines in diseases
Cytokines are proteins that are involved in cell signaling and communication during immune responses and inflammation. They modulate processes like immune cell differentiation, activation of lymphocytes and phagocytes, and the development of adaptive immunity. Corticosteroids suppress immunity by blocking cytokine synthesis and release. Cytokines play roles in diseases like cancer, rheumatoid arthritis, and septic shock by regulating immune and inflammatory processes. They can be measured clinically to monitor certain conditions.
Cortisol assays & diagnostic laboratory procedures
This document discusses cortisol measurement and its importance in diagnosing conditions like Cushing's syndrome and Addison's disease. It describes the physiology of cortisol secretion and regulation by CRH and ACTH in the HPA axis. Methods for measuring cortisol in serum, urine, and saliva are also outlined, including their advantages and disadvantages. Total serum cortisol, 24-hour urinary free cortisol, and salivary free cortisol are the main tests discussed for assessing cortisol levels.
Colorimetry
Colorimetry is a common analytical technique used in clinical laboratories to estimate biochemical substances. It involves measuring the color intensity of a colored solution, which is proportional to the concentration of the colored substance. The solution is passed through a colorimeter, which measures the amount of light absorbed. Beer's law and Lambert's law describe how the absorption is related to concentration and path length. The colorimeter contains a light source, filter to select the wavelength, cuvette to hold the sample, and detector to convert light intensity to an electrical signal. Standards and blanks are used for calibration. Colorimetry is used to estimate many substances in blood, urine, and cerebrospinal fluid.
Chromatography
Chromatography is a technique used to separate and identify the components of a mixture. It works by allowing the molecules present in the mixture to distribute themselves between a stationary and a mobile medium. Molecules that spend most of their time in the mobile phase are carried along faster. Gas liquid chromatography uses an unreactive gas as the mobile phase flowing through a tube, with an involatile liquid held on particles of a solid support as the stationary phase. Thin layer chromatography uses a liquid as the mobile phase flowing past a thin layer of powder on a solid support, with substances less attracted to the solid or more soluble in the liquid moving faster up the plate.
Chromatography
Chromatography is a technique used to separate and identify components of mixtures using the principle of partition between two phases, a stationary phase and a mobile phase. There are several types including paper, thin layer, and gas-liquid chromatography. Gas-liquid chromatography involves passing a sample through a column containing a stationary liquid phase using an inert gas as the mobile phase, which separates the components into individual peaks that can be analyzed to identify substances.
Chromatography,
Chromatography separates components of a mixture through interactions between a stationary and mobile phase. Common chromatography techniques include ion exchange, hydrophobic interaction, gel filtration, reverse phase, and affinity chromatography. These techniques separate biomolecules like proteins based on properties like charge, hydrophobicity, size, and specific binding interactions. The document provides details on chromatography components, protocols, equipment, and applications of specific techniques like ion exchange and gel filtration chromatography.

Gel electrophoresis of dna
- 1. GEL ELECTROPHORESIS OF DNA PRASAD NAIDU Msc Medical Biochemistry, Ph.D Research scholar.
- 2. WHAT IS GEL ELECTROPHORESIS? Electro = flow of electricity, phoresis, from the Greek = to carry across A gel is a colloid, a suspension of tiny particles in a medium, occurring in a solid form, like gelatin Gel electrophoresis refers to the separation of charged particles located in a gel when an electric current is applied Charged particles can include DNA, amino acids, peptides, etc
- 3. WHY DO GEL ELECTROPHORESIS? When DNA is cut by restriction enzymes, the result is a mix of pieces of DNA of different lengths It is useful to be able to separate the pieces - I.e. for recovering particular pieces of DNA, for forensic work or for sequencing
- 4. WHAT IS NEEDED? Agarose - a polysaccharide made from seaweed. Agarose is dissolved in buffer and heated, then cools to a gelatinous solid with a network of crosslinked molecules Some gels are made with acrylamide if sharper bands are required
- 5. Buffer - in this case TBE The buffer provides ions in solution to ensure electrical conductivity. Not only is the agarose dissolved in buffer, but the gel slab is submerged (submarine gel) in buffer after hardening
- 6. Also needed are a power supply and a gel chamber Gel chambers come in a variety of models, from commercial through home-made, and a variety of sizes
- 7. HOW DOES IT WORK? DNA is an organic acid, and is negatively charged (remember, DNA for Negative) When the DNA is exposed to an electrical field, the particles migrate toward the positive electrode Smaller pieces of DNA can travel further in a given time than larger pieces
- 8. A GEL BEING RUN Agarose block Positive electrode DNA loaded in wells in the agaros Black background To make loading wells easier Comb Buffer
- 9. STEPS IN RUNNING A GEL DNA is prepared by digestion with restriction enzymes Agarose is made to an appropriate thickness (the higher the % agarose, the slower the big fragments run) and ‘melted’ in the microwave The gel chamber is set up, the ‘comb’ is inserted The agarose may have a DNA ‘dye’ added (or it may be stained later). The agarose is poured onto the gel block and cooled
- 10. The comb is removed, leaving little ‘wells’ and buffer is poured over the gel to cover it completely The DNA samples are mixed with a dense loading dye so they sink into their wells and can be seen
- 11. The DNA samples are put in the wells with a micropipette. Micropipettes have disposable tips and can accurately measure 1/1,000,000 of a litre
- 12. NEXT? The power source is turned on and the gel is run. The time of the run depends upon the amount of current and % gel, and requires experimentation At the end of the run the gel is removed (it is actually quite stiff) The gel is then visualized - UV light causes the bands of DNA to fluoresce
- 13. A gel as seen under UV light - some samples had 2 fragments of DNA, while others had none or one
- 14. MORE…… Many samples can be run on one gel- but it is important to keep track Most gels have one lane as a ‘DNA ladder’ - DNA fragments of known size are used for comparison
- 15. STILL MORE…. The DNA band of interest can be cut out of the gel and the DNA extracted - Or DNA can be removed from the gel by Southern Blotting
- 16. THANK YOU
