BMEM Cryopreservation is a ready-to-use, highly optimized, chemically defined, animal component-free, cryopreservation solution for freezing human induced pluripotent stem cells (hiPSCs) and hiPSC-derived cells such as cardiomyocytes. BMEM Cryopreservation contains an optimized concentration of cryopreservation agents and a BMEM-based buffered solution for optimal cell survival during cryopreservation. BMEM Cryopreservation has been extensively tested for compatibility with hiPSC and hiPSC-derived cells. BMEM Cryopreservation is available in DMSO-based and DMSO-free versions. BMEM Cryopreservation is recommend for use with hiPSC cultured in BMEM Human Primed Pluripotent (1001) and BMEM Max Pluripotent (1004), and hiPSC-derived cardiomyocytes cultured in BMEM Protein-Free Cardiomyocyte Differentiation Kit (1003). BMEM Cryopreservation is compatible with thawing on to a variety of culture matrices, including: Corning® Matrigel® GFR, Gibco™ Geltrex™ GFR, R&D Systems™ Cultrex™ UltiMatrix GFR, SigmaAldrich® ECMatrix™-511 E8 Laminin, Gibco™ Recombinant Vitronectin, Corning® Synthemax II-SC, Acro Biosystems™ Human Laminin 521 Protein. Each lot of BMEM Cryopreservation is performance tested on hiPSC and tested for sterility.
