Dimethyl sulfoxide (DMSO) is an aprotic solvent that dissolves both polar and nonpolar compounds. Dimethyl sulfoxide has anti-freezing and bacteriostatic properties[1][2].

In Vitro

DMSO is an organic solvent that is freely miscible with water, lipids and organic agents. These properties allow for exceptional membrane penetration. The mechanism of action of DMSO is thought to be a combination of anti-inflammatory effects, nerve blockade, smooth muscle relaxation, and collagen inhibition[2].
DMSO (HY-Y0320) can be used for compound dissolution, and is not recommended for cell cryopreservation.

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
