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.
