Selection Guide

In the biopharmaceutical industry, in order to ensure high quality of products, it is often necessary to carry out clean-in-place (CIP) of chromatography systems. While the column efficiency and transfer rate of the column are also reduced due to the irreversible precipitation of denatured proteins, lipids, and DNA molecules in the sample.

0.1-1 N NaOH can effectively solve the above problems. In addition to sterilizing and inactivating viruses, it can also dissolve denatured proteins, lipids, and DNA molecules deposited on the top of the column, to extend the service life chromatography media. However, natural or recombinant protein A ligands are not tolerant to NaOH, easily getting denatured or shed.

Alkaline-tolerant Protein A Affinity Chromatography Media (Monofinity A Resin, Cat. No. L00433) is alkali-resistant Protein A affinity purification media developed by Genscript to meet the market needs. The product is made of specially engineered alkali-resistant Protein A ligand cross-linked to a novel agarose gel matrix. It has high dynamic binding capacity and low level of ligand shedding, which is suitable for purification of industrial-grade monoclonal antibodies and therapeutic Fc-Fusion proteins.
