Application

(+) Biotin NHS ester or (+)-Biotin N-hydroxysuccinimide ester has been used:


  • to biotinylate Hyb 246-4 for surfactant protein D enzyme-linked immunosorbent assay (SP-D ELISA)
  • to biotinylate proteins to form preformed complexes
  • to label and modify monoclonal anti-microfibrillar-associated protein 4 (MFAP4) (HG-HYB 7-18) to bind to alphaLISA streptavidin-coated donor beads

Biochem/physiol Actions

The N-hydroxysuccinimide ester (NHS)-biotin modification helps in the biotinylation of the target lysine residue at its ε-amino group and identifies the surface lysine residues. It is used as a tool to identify the interaction of proteins with several biological molecules, like protein-polysaccharide interactions, protein-protein interactions, protein-nucleic acid interactions, and protein-ligand interactions. NHS-biotin may be used in the biotinylation of proteins and peptides. It is typically coupled to primary amine in the pH range of 6.5-8.5.
