alt="Human Primary Cells"

Human primary cells are isolated from bone marrowcord bloodperipheral bloodand mobilized peripheral blood. Unprocessed or apheresis products are collected from IRB consented donors at one of our strategically located FDA-registered Stem Cell Collection Centers or at one of our partnering hospitals, and processed at our on-site cell manufacturing laboratory to a specific primary cell type. Cells are frozen in a controlled rate freezer at a rate of 1°C/min with a cryoprotectant solution in each vial to retain optimal viability. Frozen human primary cells are stored in a vapor phase nitrogen cryopreservation container until shipment.

How to thaw StemExpress human primary cells for optimal viability?

Primary cells are very sensitive to many aspects of the thawing procedure, such as heat, DMSO, agitation, and high centripetal forces. Obtaining high viability after thawing human primary cells can be difficult if not performed quickly and with good laboratory techniques. At StemExpress, our laboratory technicians have years of experience handling and thawing frozen human primary cells and have designed a procedure that will help you obtain the highest viability of your cells.
