Protein A

Immunoprecipitation (IP) is a classical biochemical method that enables selective enrichment of target proteins through antibody–antigen specific recognition. It is commonly used to obtain target-protein inputs with a higher signal-to-noise ratio from complex lysates, supporting Western ...

Protein A affinity chromatography exploits the high affinity between bacterial Protein A and the Fc region of IgG to achieve a one-step, highly selective capture. In industrial applications, low-pH elution and alkaline cleaning/sanitization are commonly used. After many cycles of mechanical and ...

Antibodies are valuable tools in both basic research and therapeutic applications. Protein A, Protein G, and Protein L affinity agarose beads are classical laboratory tools for antibody purification. They achieve efficient purification by specifically binding antibodies and separating them from ...
