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

Continuous Harvesting Of Extra-Cellular Proteins From Mammalian Cell Cultures Utilizing Small-Scale Perfusion
The use of a small-scale cell culture system not only maximizes the production of valuable protein but also avoids the high capital cost associated with system scale-up. Continuous harvesting can provide significant improvements in protein yields when compared to those of typical batch operations.

Economic Analysis Of Single-Use Tangential Flow Filtration For Biopharmaceutical Applications Prior to creating an accurate economic model for TFF, a thorough understanding of the process where the TFF is used is needed. A process model is a valuable tool when properly executed and it must accurately include all critical aspects of the purification process. By Michael LaBreck, Mark Perreault, Novasep
