  • NHS biotin biotinylates, amino acids, peptides or proteins under mild conditions
  • Penetrates cell membranes and can be used to label inside cells
  • Soluble in DMSO and DMF. Dissolve in DMSO or DMF prior to dilution in aqueous systems
  • NHS biotin is used to biotinylate antibodies or other proteins for detection or purification using streptavidin probes or resin
  • Forms stable amide bonds therefore the reaction is not reversable
