Reactions of MDA with primary amino groups produce inter- or intra-molecular 1-amino-3-imino-propene (AIP) bridges, leading to structural modifications of biological molecules. In this work, applying electrophoresis followed by transfer onto nitrocellulose membranes, we observed that serum of a rabbit immunized with MDA-modified lysozyme (ML) reacts not only with ML and native lysozyme (L), but also with MDA-modified ribonuclease, cytochrome c or polylysine (MR, MC and MP respectively), while it does not react with native ribonuclease, cytochrome c or polylysine (R, C and P respectively). These results confirm previous ones indicating that sera of rabbits immunized with ML contain antibodies reacting specifically with epitopes containing AIP bridges. |
