A model for the hapten-induced enhancement of monoclonal antibody binding in ELISA.
The unusual binding properties of three anti-phosphocholine (PC) monoclonal antibodies (MAbs) in ELISA has been reported [Hall T. J. (1987) Molec. Immun. 24, 773-777]. These MAbs gave reproducible 2-4 fold increases in binding to PC-protein coated plates in the presence of PC (approximately 2 mM), nitrophenyl PC (approximately 10 micron) and other PC analogues. A model is proposed here in which the complementary and opposite binding of hapten and PC-protein in the combining sites of these MAbs explains the hapten enhanceable binding in ELISA.
