Biotinylation Guidelines—Creating Biotinylated DNA

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. WebBiotinylation is an attractive approach for protein complex puriﬁ-cation due to the very high afﬁnity of avidin streptavidin for biotinylated templates.
