FreSR™-S is a defined, serum-free and animal component-free medium for the cryopreservation of human pluripotent stem cells (hPSC) as single cells. This complete and ready-to-use medium is recommended for hPSC previously cultured in mTeSR™1, TeSR™2 or TeSR™-E8™. Frozen hPSC should be stored at -135°C (liquid nitrogen) or colder.
  • Defined, serum-free and animal component-free medium for freezing ES/iPS cells as single cells
  • Quickly recover ES/iPS cell colonies after thawing
  • Reproducibly high recovery rates
  • Optimized for freezing ES/iPS cells previously cultured in TeSR™ maintenance media
  • Preserves ES/iPS cell pluripotency and expansion capacities
