Dimethyl sulfoxide, is a highly polar, aprotic organic solvent with many applications in organic chemistry and molecular biology. DMSO is routinely used in polymerase chan reaction (PCR), amplification of cDNA libraries, DNA sequencing, column-loading buffers for poly(A)+ RNA selection, buffers for the transformation of competent E. coli, and transfection protocols.

DMSO for cell culture is used as a cryoprotectant vitrification agent for the preservation of cells, tissues and organs.

DMSO's melting point is 18.5°C, it will be freezed below this temperature. Please warm it above 27°C before use.
