品名: NHS-SS-Biotin
规格: 100mg
产品描述:
NHS-SS-biotin (Succinimidyl-2-(biotinamido)-ethyl-1,3-dithiopropionate) is a long-chain cleavable amine-reactive
biotinylation reagent that has a spacer arm of 24.3 A in length due to the existence of a cross-bridge within its
chemical structure. The long spacer arm creates an increased length between a covalently modified molecule
and the bicyclic biotin rings that greatly enhances the ability of the molecule to bind to avidin or streptavidin probes.
The NHS ester group of NHS-SS-biotin reacts with the amine groups of proteins and other molecule forming an
amide bond and releasing of sulfo-NHS. NHS-SS-Biotin is a water-insoluble molecule that requires the dissolution
of organic solvents prior to be added to aqueous reactions.
