![Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media]( "Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media")
Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography MediaMonoclonal antibodies (mAbs) remain a predominant class of therapeutic protein products on the market because of their wide range of applications in disease treatment and diagnosis. Over the years, upstream technology advancements have helped improve the titer of target antibodies, from merely 1 g/L two decades ago to 10–13 g/L in fed-batch processes and up to 25 g/L in perfusion cultures today (Gronemeyer et al. 2014).

CD69 Expression On Activated Lymphocytes Is Stable In Streck's Cyto-Chex® BCT
The purpose of this study was to determine if the activation marker, CD69, is preserved and stable in whole blood samples collected in Cyto-Chex® BCT. Previous studies have demonstrated CD marker stability of whole blood samples collected in Cyto-Chex BCT for up to 7 days when stored at room temperature (18-22°C). By Jodi Alt, Ph.D
