CET's cryopreservation media is extremely versatile and can be used to freeze both adherent and non-adherent cells. Our media has been tested with hematopoietic stem cells, mesenchymal stem cells, amniotic epithelial stem cells, cancer cells, endothelial cells, fibroblastsand immune cells. Cells can then be stored on a long term basis in the vapor phase of a liquid nitrogen storage tank. Upon thawing, cells show greater than 95% viability, very little debris formation and cell death.
