Catalog	BR00028429
CAS	129179-83-5
Structure
Description	Biotin-HPDP (N-[6-(biotinamido)hexyl]-3’-(2’-pyridyldithio)propionamide), a sulfhydryl-reactive biotinylation agent, is  a water-insoluble reagent that requires the dissolution of suitable solvents, including dimethyl sulfoxide (DMSO) and dimethylformamide (DMF),  prior to the addition into aqueous reactions. Biotin-HPDP consists of a bicyclic biotin rings structure, a 1,6-diaminohexane spacer group attached to the valeric acid side chain of biotin and a sulfhydryl-reactive group at the end of the spacer. The pyridyl disulfide group at the end of biotin-HPDP is able to react with free thiol groups on proteins and other molecules forming a disulfide bond and releasing pyridine-2-thione. The long spacer arm of biotin-HPDP enables the modified molecule to better bind to the avidin or streptavidin probes.
