CryoShield Platinum™ by CellPro is a chemically defined, DMSO free cryopreservation medium designed to deliver high post thaw viability without the cytotoxic effects commonly associated with dimethyl sulfoxide. This serum free, protein free, and animal origin free formulation provides reliable protection for sensitive cells and tissues including NK T cells, CAR T cells, macrophages, induced pluripotent stem cells, embryonic stem cells, organoids, and epithelial models. The medium protects key cellular components such as membranes, mitochondria, and nuclei during freezing and thawing cycles, minimizing apoptosis, necrosis, and structural damage. CryoShield Platinum™ supports long term storage at –80°C and offers improved performance compared with many conventional DMSO containing or DMSO free cryopreservation solutions.
