A new mixed-mode chromatography(MMC) adsorbent, named Adhere NUPharose FF with functional ligand N-benzyl-N-merhylethanolamine was prepared and used for removing the leaked Protein A ligand while purifying antibody. The ligand presents hydrophobic, electrostatic and hydrogen bond interactions between Adhere NUPharose FF and adsorbate. The agarose beads were activated by allyl glycidyl ether and conditions of the activation and processes of ligand coupling on the agarose beads were optimized, leading to an a...
