Serum-free cryopreservation medium for human ES and iPS cells.

• Easy to use
• Serum-free formulation, optimised for use with TeSR™ maintenance media
• High thawing efficiencies
• Pre-screened components to ensure batch-to-batch consistency

mFreSR™ is a serum-free cryopreservation medium designed for the cryopreservation of human embryonic and induced pluripotent stem cells (ES and iPS cells). mFreSR™ contains DMSO and is complete and ready-to-use. Together with mTeSR™1 or mTeSR™ Plus, mFreSR™ eliminates the use of feeders and serum. Human ES and iPS cells cryopreserved in mFreSR™ have thawing efficiencies higher than reported conventional thawing methods using serum.
