WEBINAR: FC-FUSION PURIFICATION PERFORMANCE AND MECHANISM ANALYSIS USING AMSPHERE A3

ON DEMAND 

Join Ying Yao, JSR’s Applications Scientist, for a webinar on comparative purification analysis of Fc-fusion proteins.

In this webinar, DBC and purification properties of four commercially available Protein A chromatography resins are compared using four Fc-fusion proteins. Significant factors affecting DBC are particle size, binding capacity, and pore diffusion. The analysis of these factors showed how Amsphere A3 was able to out-perform the other three resins for three out of the four molecules tested. Join us to learn about how Amsphere A3 can support your Fc-fusion protein purification!
