EZStem™ Freezing Medium

EZStem Freezing Medium was developed to maintain xeno-free conditions during cryopreservation when culturing human embryonic stem (ES), and induced pluripotent stem (iPS) cells in a xeno-free and feeder-free environment. It is a ready-to-use solution for cryopreservation of human ES/iPS cells. Human pluripotent stem cells preserved with EZStem Freezing Medium result in high cell viability and recovery and express typical pluripotent markers after thawing. EZStem Freezing Medium has been tested on both human ES and iPS cells. Better results were obtained in comparison with both serum-containing freezing media as well as competing serum-free products, making this an ideal product for cryopreservation of valuable human pluripotent stem cells.
