Study Identifies Human Melanoma Stem Cells
Cancer stem cells are defined by three abilities: differentiation, self-renewal and their ability to seed a tumor. These stem cells resist chemotherapy and many researchers posit their role in relapse.

CellCentric And ZoBio Enter Into Partnership To Develop Lead Compounds Against Epigenetic Drug Targets
ZoBio and CellCentric are pleased to announce that the companies are working together to discover lead compounds against CellCentric’s portfolio of epigenetic therapeutic drug targets. ZoBio will use its proprietary TINS technology to screen its fragment library against targets nominated by CellCentric. Hit to lead and lead optimisation activities will be further supported by ZoBio’s biophysical and medicinal chemistry research services.

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

Improving DNA Removal from Bioprocess Purification Processes
Many new biological drug products produced using recombinant DNA technology, such as monoclonal antibodies, are produced in cell culture. Because therapeutic proteins such as monoclonal antibodies are produced in cell culture, impurities can result from the host cells, or cell substrates. By 3M Purification Inc.
