Elisa
The document discusses enzyme-linked immunosorbent assay (ELISA), including its uses, variations, and applications. ELISA uses an enzyme-conjugated antibody that reacts with a substrate to generate a detectable color change. There are several types of ELISA including indirect, sandwich, and competitive ELISA that can be used either qualitatively or quantitatively to detect antigens or antibodies. ELISA has numerous medical and industrial applications such as detecting HIV, food allergens, drugs, and various pathogens.
ELISA – Enzyme Linked Immuno Sorbent Assay
An Enzyme-Linked Immunosorbent Assay, also called ELISA or EIA.
This is quantitative immunological assay / test commonly used to detects/measure antibodies, antigens & proteins in biological samples. ( Blood, Urine, CSF etc.)
Use an enzyme to detect the binding of antigen (Ag) antibody (Ab).
The most commonly used conjugate enzyme labels are Horseradish Peroxidase (HRP) and Alkaline phosphatase (AP).
Other enzymes have been used as well; these include β-galactosidase, catalase and acetylcholinesterase.
Elisa
This document describes the enzyme-linked immunosorbent assay (ELISA) technique. ELISA is used to detect antibodies or antigens in samples. It works by affixing an unknown amount of antigen to a surface, applying a specific antibody linked to an enzyme, and detecting the enzyme's activity through a color change. There are three main types of ELISA - direct, indirect, and sandwich - which differ in their use of primary and secondary antibodies. ELISA has advantages over other techniques like radioimmunoassay in not requiring radioactive materials and being highly sensitive and specific. It has a variety of applications like diagnosing infections and measuring protein levels.

Enzyme linked immuno sorbent assay (elisa)
The document discusses the Enzyme-Linked Immunosorbent Assay (ELISA) technique, which is a biochemical assay used in immunology to detect substances like peptides, proteins, antibodies, and hormones. ELISA uses antibodies and color changing enzymes to identify these molecules in a sample. There are different variations of ELISA including direct, indirect, and double antibody sandwich ELISA. ELISA is a sensitive, cost-effective technique that can test large numbers of samples for antigens or antibodies.
ELISA
ELISA is an immunological technique used to quantitatively determine the concentration of antigens or antibodies. It was first introduced in 1971 and is similar to radioimmunoassay but uses an enzyme-linked antibody rather than a radioactive label. There are several types of ELISA including indirect ELISA, which detects antibodies; direct/sandwich ELISA, which detects antigens using two antibodies; and competitive ELISA, which measures antigen concentration by detecting free antibody binding. ELISA has many applications such as detecting antigens or antibodies in samples, determining antibody levels, and tracking disease spread.
COMPLEMENT FIXATION TEST - CFT
The complement fixation test (CFT) involves mixing antigen, antibody, and complement. If the antibody is specific to the antigen, it will bind and "fix" the complement, preventing it from lysing red blood cells. In a positive test, lysis does not occur, while a negative test results in lysis. CFT is used to detect antibodies against pathogens like syphilis, and can detect antibody levels below 1 microgram/ml. It has limitations like being time-consuming and labor-intensive. Variations involve using different complement sources or detection methods depending on the pathogen.

Indirect ELISA Protocol | St John's Laboratory
The enzyme-linked immunosorbent assay (ELISA) uses antibodies and a solid-phase enzyme immunoassay to detect the presence of a specific antigen in a liquid or wet sample. Antigens from the sample are immobilised on a solid support either non-specifically or specifically. A specific antibody is then applied over the surface so it can bind to the antigen. This antibody is linked to an enzyme or can itself be detected by an enzyme-linked secondary antibody. In the final step, a substance containing the enzyme's substrate is added. The subsequent reaction produces a visible signal, most commonly a colour change in the substrate, which indicates the quantity of antigen in the sample.
When the presence of an antigen is analysed, the name "direct ELISA" refers to an ELISA in which only a labelled primary antibody is used, whereas the term "indirect ELISA" refers to an ELISA in which the antigen is bound by the primary antibody which then is detected by a labelled secondary antibody.
Sandwich ELISA Protocol
A sandwich ELISA measures the amount of antigen between two layers of antibodies. One layer is the capture antibody, the other is the detection antibody. The antigen to be measured must contain at least two antigenic sites capable of binding to antibody, with one binding to the capture antibody and the other binding to the detection antibody.
Sandwich ELISA is very sensitive (more so than direct or indirect ELISA) and the sample does not have to be purified before analysis.

Thyroid hormone (mode of action)
The document discusses the mode of action and regulation of thyroid hormones. It states that thyroid hormones act by entering cell nuclei and binding with thyroid receptors, initiating gene transcription and protein synthesis. Thyroid-stimulating hormone (TSH) secreted from the pituitary gland is the major regulator of thyroid hormone production and release. TSH levels are controlled by thyrotropin-releasing hormone from the hypothalamus through a negative feedback loop with thyroid hormones. A number of other factors also influence thyroid secretion.
Ticplant Lesson
Vascular plants contain tubes that transport water and nutrients throughout the plant from roots to stems and leaves. They also contain tubes that transport food made in the leaves to other plant parts. The main plant parts are roots, stems, leaves, and reproductive organs. Roots take in water and nutrients from soil. Stems transport water between roots and leaves and food between leaves and other plant parts. Leaves make food through photosynthesis that is transported through the plant. Reproduction involves pollen carrying the male nuclei fertilizing the female egg cells in ovaries to form seeds in fruits.
cardiac physiology
The document summarizes key aspects of cardiac physiology, including:
- The functions of the heart in generating blood pressure, routing blood flow, ensuring one-way flow, and regulating blood supply.
- The cardiac cycle and its phases of isovolumic contraction, ejection, isovolumic relaxation, and diastole.
- Factors that affect cardiac output including venous return, heart rate, contractility, and peripheral resistance.
- Key reflexes that regulate cardiac function such as the baroreceptor, chemoreceptor, and Bezold-Jarisch reflexes.
Brugia malayi
Brugia malayi is a parasitic roundworm commonly known as the Malayan filaria. It is transmitted by mosquitoes in tropical freshwater areas, especially in parts of Asia. The microfilariae have a nocturnal periodicity and are ingested by mosquitoes during blood feeding, where they develop into infective L3 larvae. These larvae are then transmitted to other humans during subsequent mosquito bites, developing into adult worms that reside in the lymphatics and blood, causing diseases such as elephantiasis.
Thyroid hormone by Dr. Anurag Yadav
The thyroid gland secretes the major hormones thyroxine (T4) and triiodothyronine (T3), which are controlled by thyroid stimulating hormone (TSH) from the pituitary gland. T4 and T3 are bound to plasma proteins and transported throughout the body, where a small unbound fraction exerts biological effects. The thyroid hormones regulate growth, development, metabolism, and other physiological processes. Thyroid function is tested by measuring T3, T4, TSH, and other markers. Disorders like hypothyroidism and hyperthyroidism can be treated with thyroid hormone supplements or inhibitors.
RIA and ELISA
The following presentation contains helpful information regarding Radioimmunoassay (RIA) and Enzyme-Linked Immunosorbent Assay (ELISA), including their history, introduction, advantages, procedures and applications.
ELISA Vs ELISPOT - Principle, Procedure, Advantages
The Enzyme Linked Immunospot (ELISPOT) technique was developed by Cecil Czerkinskdy in 1983. ELISPOT is used for the detection of secreted proteins, such as cytokines and growth factors. ELISPOT is primarily used in immunology research in the following areas:
Brugia malayi
Brugia malayi is a roundworm nematode that is one of three causative agents of lymphatic filariasis in humans, along with Wuchereria bancrofti and Brugia timori. It infects 13 million people in parts of Asia, causing lymphatic filariasis which is characterized by swelling of the lower limbs. The life cycle of B. malayi involves transmission via mosquito vectors to humans, where it resides in the lymphatic system and can cause symptoms such as lymphadenitis, lymphangitis, and long term lymphedema known as elephantiasis. Diagnosis involves identification of microfilariae in blood smears taken at night,
Labeled assays
This document provides an overview of basic immunologic procedures used in labeled immunoassays. It describes key terminology like ligands, receptors, sandwich technique and different types of immunoassays including ELISA, RIA, IRMA, fluorescent and chemiluminescent assays. Radioimmunoassays use radioactive labels while enzyme immunoassays use enzymatic labels that are detected through reactions with substrates. The document also discusses various labeling techniques, assay formats (e.g. competitive, non-competitive, homogeneous, heterogeneous), applications and advantages/disadvantages of different immunoassay methods.
Immunoassay
Chemiluminescence is the emission of light from a chemical reaction and can be used for analytical testing. It involves reactions that produce electronically excited molecules that then decay to ground state while emitting photons of light. Common substances used include luminol, acridinium esters, and ruthenium derivatives. When oxidized, typically with hydrogen peroxide, intermediates are produced in excited states. As they return to ground state, light is emitted. This light can be measured with high sensitivity for applications like immunoassays, liquid chromatography detection, and clinical diagnostics. Advantages include stability, low toxicity, high sensitivity down to attomole and zeptomole levels, and fast results.

3. Key aspects of performing ELISA are discussed such as sample treatment and storage, controlling humidity and air flow during incubations, and troubleshooting poor results. Direct, indirect, sandwich, and competitive ELISA techniques are also summarized.
B Cell Development
- B cell development begins with stem cells in the bone marrow, where they undergo a series of differentiation stages defined by immunoglobulin gene rearrangement under the influence of cytokines and contact with stromal cells.
- Successful rearrangement of the heavy and light chain genes leads to expression of a B cell receptor (BCR) and selection of clones that do not recognize self-antigens through deletion, anergy or receptor editing.
- Mature B cells that pass self-tolerance checkpoints are exported from the bone marrow to the peripheral immune system.

Radioimmunoassay is an immunoassay technique that uses radiolabeled antigens or antibodies to detect and quantify antigens or antibodies in a sample. It involves competitive binding between the radiolabeled and unlabeled antigens or antibodies. The amount of radiolabeled antigen or antibody bound is inversely proportional to the concentration of the unlabeled antigen or antibody in the sample. RIA is highly sensitive and specific due to the immune reaction between antigens and antibodies. It has applications in endocrinology, pharmacology, oncology, and epidemiology to detect hormones, vitamins, drugs, and infectious disease markers.
Radio immuno assay
Radioimmunoassay was introduced in 1960 as an assay for measuring insulin levels in plasma. It represented the first invitro technique for detecting hormone levels in blood. The technique uses radioactive labels on antigens or antibodies to allow quantification of antigens or antibodies in a sample by competing them against known standards in binding to antibodies or antigens. It provides a highly sensitive method for detecting hormones, drugs, toxins, and other molecules and has revolutionized research and clinical practice.

HOMEOSTASIS
The document discusses body fluid homeostasis and the mechanisms that regulate fluid balance and thirst. It describes how osmotic pressure gradients maintain equilibrium between intracellular and extracellular fluid, and how the kidneys, vasopressin, and the renin-angiotensin system help regulate fluid levels. Small increases in vasopressin lead the kidneys to conserve water, while thirst only occurs if this buffering is insufficient to correct cellular dehydration. The neural pathways and hormones that detect changes in fluid volume or osmolality and trigger thirst or salt appetite are also outlined.

Elisa
- 1. ELISA PART 2
- 2. ELISA • Indirect sandwich assay – “Indirect” because the color reaction is catalyzed by an enzyme linked to a secondary Ab (and not the primary Ab) – “sandwich” because the antigen Ab we’re trying to detect is attached between the substrate attached Ab and the detecting primary Ab
- 6. Identification of an “unknown” antibody • You will be given a sample of a mouse antibody with one or more of the following serotypes – IgG1, IgG2a, IgG2b, IgG3, IgM, IgA • Remember, antibodies are HIGHLY specific and can distinguish between the different types of IgG used
