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
DOWNSTREAM PROCESSING PRODUCTS
Resin are designed specifically for intermediate purification steps that remove host-cell contaminants from partially purified targets using strong or weak hydrophobic interactions. Methacrylate-based beads for protein and nucleic acid purification using hydrophobic interactions are available for purifying compounds that have weak or strong hydrophobic regions.
Sartopure PP2 Cartridges were optimized for the wide range of prefiltration.
