DTSSP (Highly Pure) by Molecular Depot is a 3,3′-dithiobis(sulfosuccinimidyl propionate), known as DTSSP, used for protein crosslinking studies. The reagent carries a succinimidyl ester at each end to react with lysine amines, a disulfide in the middle that a reducing agent cleaves, and sulfonate groups that make it water-soluble and membrane impermeant. It is used to crosslink proteins and map protein interactions, to stabilise complexes before analysis and in protein chemistry research. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
