Serum-Free Cell Store Freezing (for Stem Cells, DMSO-Free) is a specialized cryopreservation medium designed for a wide range of stem cells and cell lines. It is chemically defined, serum-free, protein-free, DMSO-free, and free of animal-derived components. The formulation consists of cryoprotectants, inorganic salts, sugars, and other defined ingredients to support high post-thaw viability and functionality of sensitive stem cells. Features Chemically defined formulation – free of animal-derived components and exogenous proteins. Serum- and protein-free – contains no bovine serum or other proteins, eliminating the risk of introducing contaminants to cell stocks. Advanced cryoprotection formula – enables direct placement of cells into a –70°C (or –80°C) freezer without the need for controlled-rate or stepwise cooling. Components Components No. Name 40154ES60 40154 Serum-Free Cell Store Freezing ( for Stem cell, DMSO - free) 100 mL Storage This product should be stored at 2~8℃ for 1 year. Figures 1. High Post-Thaw Viability Figure 1. High Post-Thaw Viability. Post-thaw viability of cells cryopreserved at 5 × 10⁶ cells/mL using different freezing media. Results show that Yeasen’s DMSO-free formulation provides comparable or superior viability compared to both DMSO-containing and DMSO-free formulations from Supplier A*. This highlights Yeasen’s effectiveness in maintaining cell viability without the use of DMSO. Documents: Safety Data Sheet 40154_MSDS_HB260109_EN.PDF Manuals 40154_Manual_Ver.EN20260109.pdf
