Description | Biotin disulfide-N-hydroxysuccinimide ester.Succinimidyl-2-(biotinamido)-ethyl-1,3-dithiopropionate. NHS-SS-Biotin is an amine-reactive biotinylation reagent that contains a reducible disulfide. NHS-SS-Biotin is cell membrane per-meable and has a long chain separating the biotin group from the amino-reactive NHS-ester N-Hydroxysuccinimide ester. This product is often used to purify an antibody or other protein from a biotin specific affinity resin like immobilized streptavidin without exposing your protein of interest to denaturing conditions. Biotinylation reagent incorporating a spacer with a cleavable disulfide linkage. Typically coupled to primary amine in the pH range 6.5-8.5. Cleavage of disulfide requires reducing agent allowing mild recovery of biotinylated compound. |
