Biotinylation reaction
Webbiotinylation. The covalent linking of biotin to a protein, peptide, nucleic acid (DNA, RNA) or other biomolecule of interest, which in turn binds with high affinity to avidin or streptavidin … WebBirA is ideal to add biotin to a protein that contains an AviTag. The distinct advantage of enzymatic biotinylation using the AviTag is the control conferred on the location of the tag and the number of biotin molecules that can be appended. In this respect the enzymatic reaction is superior to chemical biotinylation using NHS-sulfo-biotin ...
