DMSO has various functions in the Biotechnology segment. DMSO is useful in cryopreservation of cells and can be used to purify proteins. The solvent properties may be useful for synthesis or drug delivery of proteins, peptides or carbohydrates.

Cryopreservation: A unique combination of physical properties has established DMSO as the standard solvent for the preservation of human stem cells, bone marrow and other tissue.

Histology and cytology: DMSO significantly enhances the infiltration of color or paraffin wax during tissue processing.

Peptide Synthesis: DMSO is used as a reaction solvent.
