Thermo Scientific™ Pierce Dimethylsulfoxide (DMSO) is a sequencing-grade preparation with high purity and consistent absorptivity properties for use in HPLC and mass spectrometry methods.nn nnA sequencing-grade preparation with high purity for use in traditional amino acid analyzers and other high-volume applications.nnThis sequencing-grade dimethylsulfoxide is >99.5% pure DMSO. The economically priced 950mL bottles are an excellent choice for protein and peptide applications that requiring large volumes of the water-miscible solvent. The 50mL bottles are provide convenience and minimize waste for small dissolution and reaction volumes. The purity test ensures that preparation is essentially devoid of amines. The formulation was originally developed for peptide sequencing applications with amino acid analyzers, which required high purity solvent and an affordable price. This DMSO is packaged in solvent-rinsed amber glass bottles and sealed with PTFE-lined fluorocarbon caps for ultimate protection.
