| NHS-SS-11-Biotin | NHS-SS-11-biotin 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-11-biotin reacts with the amine groups of proteins and other molecule forming an amide bond and releasing of sulfo-NHS. NHS-SS-11-Biotin is a water-insoluble molecule that requires the dissolution of organic solvents prior to be added to aqueous reactions. Group: Biotinylation reagents. CAS No. 142439-92-7. Molecular formula: C22H33N5O7S3. Mole weight: 575.72 g/mol. Appearance: A solid. Purity: 0.98.
