General description

Dimethyl sulfoxide is an amphipathic molecule, soluble in both aqueous and organic solvents. It is commonly used as an aprotic solvent and also as a reagent in organic synthesis.

Application

DMSO has been used as a medium to prepare a chemiluminescence reagent that can be a substitute to commercially-available enhanced chemiluminescence kits for use in immunoblotting technique.

Biochem/physiol Actions

DMSO is a highly polar substance that can be used as an industrial solvent for organic and inorganic chemicals. It is also used as a protectant during cold storage of living cells. It is also useful for the oxidation of thiols and disulfides to sulfonic acids.

Packaging

Note: D5879-1L in plastic jerricans
