STEM-CELLBANKER GMP Grade is a chemically defined freezing medium optimized for stem cell cryopreservation. STEM-CELLBANKER is serum-free and does not contain any animal-derived components; for additional flexibility, it is available with or without DMSO. STEM-CELLBANKER has been used to successfully freeze and thaw a variety of stem cell types, including embryonic and mesenchymal stem cells, marrow- or umbilical cord blood-derived stem cells, and iPS cells. After thawing, cells frozen with CELLBANKER products consistently have high cell viability (approximately 90% for most cell lines). This GMP-grade medium is manufactured under rigorous standards to ensure high quality and consistency, in a facility compliant with GMP regulations and guidelines.
