  • dimethyl sulfoxide reference solvent

    General description Dimethyl sulfoxide (DMSO) is an effective aprotic solvent, colorless, odorless, and naturally hygroscopic. DMSO can enhance the permeability of various hydrophilic and lipophilic permeants. It is one of the most widely used laboratory solvents. Apply Dimethyl sulfoxide (DMSO) is used as a compound detection tool in various experimental studies. In the amyloid beta beta aggregation experimental protocol, it can be used as a solvent to redissolve the polypeptide to maintain its dissociated state. Look out Products that are prone to excessive cooling and slowly melt and solidify at room temperature can be liquefied again at room temperature without affecting themselves. Other instructionsDimethyl sulfoxide standardDimethyl sulfoxide (DO) is an organic compound that is often used as a solvent, reaction reagent and catalyst carrier. Due to its chemical properties, it may be regulated as a laboratory reagent. Here are some possible relevant standards for DMSO:1. Purity standards: DMSO used in…
