Biotinylation of proteins
WebBiotinylation is the labeling of biotin to a molecule of interest such as a protein, antibody, peptide, or other biomolecule (Figure 1). Biotinylated proteins typically retain biological … WebChemical biotinylation of proteins using a biotin-X-NHS-Ester (1). NHS-biotin contains a cleavable disulphide bond so the desired protein can be easily cleaved from the biotin/streptavidin complex (2). Thiol-cleavable NHS-activated biotins react efficiently with primary amine groups (-NH 2) in pH 7-9 buffers to form stable amide bonds.
