Three systems--the indirect, peroxidase-antiperoxidase (PAP), and avidin-biotin peroxidase complex (ABC) detection system--were compared in quantitative ELISA titration and inhibition assays and tissue labeling with keratin antisera. By labeling a detection enzyme such as horseradish peroxidase with biotin, and a secondary antibody (reactive against the antigen detecting primary antibody) with biotin as well, these two compounds can then be linked irreversibly with avidin. The mutation destabilizes the enzyme, facilitating active biotin molecules (biotinoyl-5-AMP) to dissociate and bind to primary amines of exposed lysine residues on adjacent proteins. It contains four identical subunits having a combined mass of 67 to 68kDa. A commonly used marker is Ki-67, which was discovered at Kiev University, Ukraine. Furthermore, because of the very strong affinity for biotin, incubation periods for either pre-immobilization of the antibody or the antibody-antigen complex are more consistent, with only target concentration, sample viscosity and volume being major sources of variability. The avidin-GdL 3-4 complexes thus obtained exhibit changes in both r1 and r2 that are pH dependent. 1978 Jun 15;87(1):114-26. doi: 10.1016/0003-2697(78)90575-4.
