Cryopreserving of the cells is a critical step to ensure quick and reliable results when performing stem cell culture. REPROCELL's freezing medium was formulated by the stem cell expert Prof. Nakatsuji and his colleagues at Kyoto University for human ES/iPS cells. It ensures high levels of viability, up to 10% of the input cells, which is more than 10 times greater than the typical viability obtained with 10% DMSO solution.

Serum-free, Ready-to-use. Store at − 80°C for long term storage.
