Ph of biotin

WebSulfhydryl biotinylation is performed at a slightly lower pH (6.5-7.5) than labeling with NHS esters. Besides whole proteins, biotinylated peptides can be synthesized by introducing a cysteine (Cys) residue during synthesis at the terminus of the amino acid chain to get a site specific and oriented biotinylation. WebAlternatively, 2-iminobiotin the cyclic guanidino analog of biotin could be used since it exhibits a pH-dependent interaction with streptavidin that facilitates recovery under milder conditions as well. It retains high-affinity specific binding at high pH but interacts poorly at acidic pH values. Alternatively, biotin with cleavable spacers can ...
