HyClone HyCryo-STEM medium is a serum-free product intended for cryopreservation and storage in biomanufacturing of stem cell lines. The medium is designed for use with neural progenitor or stem cells, embryonic stem cells (ESCs), and induced pluripotent stem (iPS) cells. This chemically defined formulation contains DMSO and protein components to protect cells during the cryopreservation process. HyCryo-STEM medium is provided at a 2× concentration to be added to cells resuspended in their own conditioned or fresh growth medium.
