Biotin/Avidin Binding Purification

Introduction of Biotin/Avidin Binding

The biotin-avidin system (BAS) is a protein-ligand interaction system that exists in nature. This system has been successfully used in the detection and purification of proteins, nucleic acids, and lipids. BAS can be combined with affinity chromatography to greatly improve the purity of purified proteins, or to find receptors for known ligands. This method is widely used in the drug research and development industry. When a drug molecule has a therapeutic effect but it is not clear which protein it specifically acts on, it can be biotinylated and then the target protein can be captured from thousands of proteins.

The Superiority of His-Tag Purification

• High sensitivity to improve the accuracy of the detection method
• High specificity due to the high affinity between avidin and biotin
• Universal and multifunctional
• High stability reduces operational errors and improves measurement reliability.
• Multi-stage signal amplification can maintain the original biological activity of macromolecular substances.
