Comparing Protein A Resins for Monoclonal Antibody Purification
Protein A is the affinity chromatography ligand of choice for the first antibody capture step, because its high selectivity gives excellent purity (typically > 99%) and high yields. Furthermore, Prote…

Innovative Chromatography Resins Can Improve Purity and Quality
“The problem is that, with every DSP step, product yields decrease, while bioprocessing time and equipment occupancy goes up, along with DSP manufacturing risks,” Schub says.
He also emphasizes th…

The Challenge of Disruptive Technologies in Bioprocessing
Purification can typically include four to five chromatography steps, which results in a product yield that decreases with each step that is added. Because product yield drives the cost of goods (COG)…

The Development and Application of a Monoclonal Antibody Purification Platform
Initially, several range-finding experiments were carried out to determine the optimal parameters for each unit operation and to maximize the yield and purity for that particular antibody. We used the…
