CP-1(R) High Grade

For cryopreservation of hematopoieticstem cells, dimethyl sulfoxide (DMSO) has generally been used as a cryoprotectant.
In the case ofcryopreservation with DMSO alone, it was common to be stored in liquid nitrogen (-196° C) after frozen by the stepwisefreezing method with a program freezer. However, from the early 1980' s, simple cell freezing methods that do not use a program freezer have been studiedusing DMSO and hydroxyethyl starch (HES) for hematopoietic stem cells in bone marrow.
In Japan, studies on application of simple cell freezing method using DMSO and HES toperipheral blood stem cells have beenadvanced, and the optimum concentrations of HES and DMSO in the simple cell freezing method were decided 6% HES, 5% DMSO. This simple cell freezing method enabled stable cryopreservation for a short period of time (6 months to 1 year and a half) using a -80° C freezer without stepwise freezing method.
