A rapid and simple antibody purification method is reported for the isolation of monoclonal antibody IgG1 from SARS-CoV N protein rabbit serum by using surface-modified magnetic beads. First magnetic poly (methacrylate-divinylbenzene) (PMA-DVB) beads were prepared and modified with aldehyde end group through surface chemical reactions. Then protein A were covalently bound to aldehyde-activated magnetic beads and further used to purify monoclonal antibody IgG1 from rabbit serum directly. This rapid magnetic carrier technology proves to be efficient and rapid for antibody purification and has potential to massive production of monoclonal antibody.

Monoclonal antibodies are conquering the biopharmaceutical market because they can be used to treat a variety of diseases. Therefore, it is very important to establish robust and optimized processes for their production. In this article, the first step of chromatography (Protein A chromatography) in monoclonal antibody purification was optimized with a focus on the critical elution step. Therefore, different buffers (citrate, glycine, acetate) were tested for chromatographic performance and product quality. Membrane chromatography was evaluated because it promises high throughputs and short cycle times. The membrane adsorber Sartobind® Protein A 2 mL was used to accelerate the purification procedure and was further used to perform a continuous chromatographic run with a four-membrane adsorber-periodic counter-current chromatography (4MA-PCCC) system. It was found that citrate buffer at pH 3.5 and 0.15 M NaCl enabled the highest recovery of >95% and lowest total aggregate content of 0.26%. In the continuous process, the capacity utilization of the membrane adsorber was increased by 20%.
