Cell Freezing Media and Reagents

The ability to successfully freeze cells and resuscitate them from liquid nitrogen storage is one of the most important aspects of cell culture research. Preventing ice crystal formation in particular is paramount to maintaining cell viability during cryopreservation. We offer an extensive line of sterile-filtered, application-tested cryoprotectants like DMSO as well as ready-to-use cell freezing media that are designed to maximize cell viability during the freezing and thawing processes.
