MACGEN's CryoSafe Serum-free Cryoprotection Media is a cryopreservation medium containing fetal bovine serum (FBS). CryoSafe Serum-free Cryoprotection Media is packaged as a 1X concentrate. We have created a new type of cryopreservation medium that can preserve almost any cell type at - 80°C (or in liquid nitrogen if you prefer). The simple procedure allows your lab to avoid complicated freezing steps. CryoSafe Serum-free Cryoprotection Media provides animal component-free (ACF) conditions during biopreservation, essential to maintaining consistency when culturing cells in ACF systems with proven reliability and consistency after cold freezing and thawing processes.
