 Biotin, a 244Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for avidin (Ka=1015 M-1) and streptavidin (Ka=1015 M-1). Biotin and (strept)avidin interaction is rapid and once the bond is established it can survive up to 3M guanidine-hydrochloride and extremes of pH. Biotin-avidin bonds can only be reversed by denaturing the avidin protein molecule with 8M guanidine-hydrochloride at pH1.5 or by boiling in SDS Page Sample Loading Buffer.

HOOK™ BiotinQuant™ uses HABA (2-(4-Hydroxyphenylazo)benzoic acid/ 2-(4′-Hydroxybenzeneazo)benzoic acid/ 4′-Hydroxyazobenzene-2-carboxylic acid) to rapidly estimate the mole-to-mole ratio of biotin to antibody or protein.   The method of biotin incorporation estimat..
