Binding with lysozyme of antibodies against surface-simulation peptides representing the lysozyme antigenic sites.
Previously it had been shown that native lysozyme has three discontinuous antigenic sites (comprising spatially adjacent residues that may be distant in sequence) that were mimicked by surface-simulation synthetic peptides that had the capacity to bind the bulk (97-99%) of the antibody response against native lysozyme. In the present work these three surface-simulation synthetic peptides were coupled to succinoylated bovine serum albumin, and the conjugates were injected into rabbits. Antibodies against each peptide reacted, as expected, only with that peptide, but it was also found that the antibodies could bind with lysozyme, and the complete specificity of this binding was rigorously established. The advantages of these findings in conformational and immunological investigations are outlined.
