Immunological relevance of malonic dialdehyde (MDA): II. Precipitation reactions of human sera with MDA-crosslinked proteins.

Using precipitation reactions in agarose gels (Bidimensional double diffusion: Ouchterlony. Counterimmunoelectrophoresis: CEP), we showed that: a) sera from normal human subjects contain components able to bind and precipitate with MDA-crosslinked lysozyme (ML) and not with native lysozyme, which indicates that the chemical structures involved in such bindings arise from reaction of MDA with lysozyme and probably include 1-amino-3-iminopropene (AIP) bridges. b) some if not all of these seric components are immunoglobulins. c) the F(ab')2 regions of these immunoglobulins are involved in their binding and precipitating properties. These results lead us to assume that sera from normal human subjects contain immunoglobulins with antibody-like specificity for MDA-crosslinked proteins. Nevertheless, this assumption remains to be assessed by further studies, especially about the "epitopes" involved in such reactions.
