Cell Reservoir One is a serum-free cell culture freezing medium, which contains a water-soluble glycoprotein SERICIN isolated from the silkworm cocoon as a major constituent. SERICIN shows the same high efficacy of cryopreservation as with FBS, and reduces the cell toxicity of DMSO. As DMSO is known to have adverse effects on cellular functions, especially Embryonic Stem Cells, Cell Reservoir One is available both with and without DMSO. » Unnecessary programming freezer or special vessel» Ready-to-use solution» Serum-free with no animal derived components» High cell recovery and viability
