Description

General description

Dimethyl sulfoxide (DMSO) is an effective aprotic solvent. It is colorless, odorless and hygroscopic in nature. DMSO enhance the permeability of various hydrophilic and lipophilic permeants. It is one of the widely used solvents in the laboratory.

Application

Dimethyl sulfoxide (DMSO) has been used as a vehicle for test compounds in various experimental studies. It has also been used as a solvent during amyloid β (Aβ) aggregation protocol for resolubilization of peptide to maintain its dissociated state.
