CryoStor® Freeze Media

CryoStor cryopreservation freeze media products have been designed to mitigate temperature-induced molecular cell stress responses during freezing and thawing. CryoStor proprietary freeze media products are intended for cryopreservation of biologics at -70 to -196°C and are based on the novel HypoThermosol formula. All CryoStor products are pre-formulated with USP grade DMSO, a permeant solute cryoprotective agent which helps mitigate damage from the formation of intracellular ice. Across a broad spectrum of cell types, CryoStor products have proven much more effective in reducing post-preservation necrosis and apoptosis as compared to commercial and home-brew isotonic and extracellular formulations. This enables greatly improved post-thaw cell yield, viability, and recovery. CryoStor products meet USP <71> Sterility and USP <85> Endotoxin testing standards, and are manufactured under cGMP.


CryoStor is offered in several packages and pre-formulated with DMSO in final concentrations of 2%, 5%, and 10%.

CryoStor CS10 Freeze Media

Pre-formulated with 10% DMSO, CryoStor CS10 has demonstrated remarkable biopreservation efficacy in numerous cell types, including sensitive cells such as hepatocytes.  Now available in 1000 mL Bags and Single-Use Syringes.


CryoStor CS5 Freeze Media

Pre-formulated with 5% DMSO, CryoStor CS5 routinely outperforms competing freeze media containing 10% DMSO and is recommended for cryopreservation of most cell types.


CryoStor CS2 Freeze Media

Pre-formulated with 2% DMSO. In some cell types, CryoStor CS2 has demonstrated biopreservation efficacy at or above the levels of competing commercial and in-house formulated freeze media, even in the presence of greatly reduced levels of DMSO.
