Ion exchange chromatography and affinity chromatography

  1. 1. Presented By ; BRITTO SAMUEL M II M.Sc., BIOTECHNOLOGY DEPARTMENT OF BIOTECHNOLOGY, AVS COLLEGE OF ARTS AND SCIENCE, SALEM
  2. 2. *Chromatography is a useful method of separating many different kinds of chemical mixtures. *Chrom- Color separation of chemical components based on colors (Paper Chromatography). Components ; *The mixture is dissolved in a fluid called the ”mobile phase” *Which carries it through a structure holding another material called the stationary phase *The separation is based on differential partitioning between the mobile and stationary phases. *Chromatography may be preparative or analytical.
  3. 3. *Chromatography was first employed in Russia by the Italian-born scientist Mikhail Tsvet in 1900 research in plant pigments such as chlorophyll, carotenes, and xanthophylls *New types of chromatography developed during the 1930s and 1940s made the technique useful for manyseparation processes. * Archer John Porter Martin and Richard Laurence Millington Synge during the 1940s & 50s established the principles and basic techniques of partition chromatography *Tsvet's chromatography could be applied in many different ways, resulting in the different varieties of chromatography Separated color of plant pigment
  4. 4. *In any chemical or bioprocessing industry, the need to separate and purify a product from a complex mixture is a necessary and important step in the production line. *chromatography can purify basically any soluble or volatile substance if the right adsorbent material, carrier fluid, and operating conditions are employed. *chromatography can be used to separate small products since the conditions under which it is performed are not typically severe. For these reasons, chromatography is quite well suited to a variety of uses in the field of biotechnology, such as separating mixtures of proteins.
  5. 5. *Ion Exchange Chromatography *Affinity Chromatography
  6. 6. Ion-exchange chromatography
  7. 7. *Ion chromatography (or ion-exchange chromatography) is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. * Proteins, small nucleotides, and amino acids are also purified using Ion exchange Chromatography * The water-soluble and charged molecules such as proteins, amino acids, and peptides bind to oppositely charged by forming covalent bonds to the insoluble stationary phase *This method applies the idea of the interaction between molecules and the stationary phase which are charged oppositely to each other. *The bound molecules then can be eluted and collected using an eluent which contains anions and cations by running higher concentration of ions through the column or changing pH of the column.
  8. 8. * Column containing anion exchanger . *The sample is poured into the column. *Anion presented in the Column is bind with the sample which having cations. *During this process, unbounded samples inside the column get eluted. *Changing pH, adding some buffers helps to elute the sample outside. Information: column containing anion exchanger this binds with the sample and make the unbounded samples to be eluted.

  10. 10. * Two type of buffers to be used in Ion Exchange Chromatography. > Cation Buffer > Anion Buffer Cation Buffer: used for anion exchanger for product retrieval Anion Buffer: Used for cation exchanger for product retrieval
  11. 11. *Resin exchanger used for separating the small particles *Cellulose, Dextrin, Polyacrylamide exchangers used for proteins and polysaccharide purification *Dextran and Polyacrylamide exchangers used for separation of nucleotides, amino acids, Vitamins.
  12. 12. * The process of chromatography depends upon affinity between sample and ligands. * Based on attraction between the sample and ligand this process succeed. * Otherwise said to be Preparative Chromatography. * Process fast separation. Principle • Works on the principle of attraction or charm between the sample and ligand Affinity chromatography works. • Affinity – Attraction , Kinship, Relationship. • Because of the process of attraction, this process termed to be Affinity Chromatography. • The principle of affinity chromatography is that the stationary phase consists of a support medium (e.g. cellulose beads) on which the substrate (or sometimes a coenzyme) has been bound covalently, in such a way that the reactive groups that are essential for enzyme binding are exposed.
  13. 13. *Three Process progressed behind Af-Chromatography. 1. Matrix :used for ligand attachment 2. Ligand : used to bind on the space of interaction 3. Attachment of Matrix with Ligand A special tool used to bind the ligand to the matrix is “Spacer Arm”
  14. 14. *Addition of the sample inside the column. *Column already containing ligand. *Addition of sample to the column leads to binding of ligand to the sample. * Matrix helps to bind the sample to the ligand. *Spacer arm present between the matrix and ligand helps to hold the ligand matrix this leads to binding of the sample to the ligand. *In this process, the purified materials like proteins get attached with the ligand. Rest of the rusts eluted out. *Due to changing of pH or addition of buffers in the column helps to elute our desisted product.
