Avidin-biotin Complexes for Affinity Chromatography

The specific interaction between biomolecules has high binding force, such as antigen-antibody interaction, enzyme-substrate interaction, hormone-receptor interaction and biotin-avidin interaction, etc. The separation principle of affinity chromatography is based on the immobilization of affinity-based biomolecules on an insoluble matrix, and the use of high-efficiency affinity energy can purify another molecule. The ligands immobilized on the matrix can be used to purify antibodies, enzymes, hormones and other biomolecules through interaction. The biotin-avidin system has the strongest known non-covalent interaction force and can be used for affinity chromatography of biomolecules. Biotin columns are based on biotin for the separation of avidin, streptavidin, anti-biotin antibodies and avidin conjugates for further separation and characterization.

Biotin-avidin system for affinity chromatography

Choosing the right affinity adsorbent is a key factor for efficient affinity chromatography. The biotin-avidin system can be used for affinity chromatography, with biotin as the matrix ligand, which can be used for efficient purification of avidin, streptavidin, anti-biotin antibodies and avidin conjugates. The choice of affinity chromatography matrix needs to take into account the following factors:

• Stable physical and chemical stability
• High affinity for ligand
• The structure of the matrix has a porous network structure
