How to Optimize Protein G Column Antibody Purification Effectively?
When I first started working with antibody purification, I quickly realized how critical optimization was for ensuring consistent and high-quality results. Protein G column antibody purification is one of the most reliable techniques for isolating antibodies, but the effectiveness of the process depends heavily on how it’s carried out. Over the years, I’ve refined my approach, learned from mistakes, and developed practical methods to make this process both efficient and reproducible. In this article, I’ll walk you through the key steps, insights, and tips that can help you optimize Protein G column antibody purification effectively. Understanding Protein G Column Antibody Purification Protein G is a bacterial cell wall protein that binds strongly to the Fc region of IgG antibodies from many species. By immobilizing Protein G on a chromatography resin, we can selectively capture antibodies from complex biological samples such as serum, ascites fluid, or cell culture supernatants....
