Dimethylsulfoxide (DMSO)

Description

ATCC supplies this dimethylsulfoxide (DMSO) product, which is graded for use in biological and cell culture applications. Its primary role is as a cryoprotectant for the preservation of cell lines and other biological specimens. The reagent is tested to ensure it is non-cytotoxic at working concentrations and effective for maintaining cell viability during freeze-thaw cycles. DMSO facilitates cryopreservation by permeating cell membranes and depressing the freezing point of intracellular fluid, thereby reducing the formation of damaging ice crystals. This mechanism is essential for the successful long-term storage of sensitive cellular material in biobanks and research laboratories.
