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 ...
In His-tag affinity purification, Ni²⁺-NTA/IDA resins gradually lose performance due to fouled coordination sites, metal loss, and pore clogging, manifested as reduced binding capacity, increased nonspecific adsorption, and elution tailing. Periodic “strip–clean–recharge” maintenance restores ...
