Ensuring Viral Safety of Viral Vaccines and Vectors
Limitation of this method is the flow rate of the fluid, which needs to be modulated for optimal results (21).
Gamma irradiation—ionizing radiation from a radioactive Cobalt 60 source—breaks bo…

Development of Purification for Challenging Fc-Fusion Proteins
In most two-column downstream processing platforms, the first column is Protein A (ProA), which binds the target mAb directly from the harvested cell culture fluid. A low pH buffer is routinely used t…
