Production and application of monoclonal antibodies suitable for the specific detection of listeria monocytogenes

TL;DRAbstract

The principal objective of this research concerned the production, characterisation and application of antibodies for the specific detection of Listeria monocytogenes.
\n
\nMonoclonal antibodies were generated against various L. monocytogenes-derived antigens. Initially, a panel o f antibodies was produced against a 60 kDa extracellular protein isolated from exponentially growing L. monocytogenes culture supernatants.Subsequently, the L. monocytogenes-speclfic surface pathogenicity protein, Intemalin B (InlB), was biochemically isolated and used to generate InlB-specific monoclonal antibodies. The specific reactivity of these antibodies was demonstrated using purified recombinant InlB (rlnlB) and p60 (rp60) proteins, respectively. However, the anti-p60 antibody was cross-reactive with certain non-pathogenic members of the Listeria genus and the anti-InlB monoclonal antibody was not capable of efficiently binding InlB on the L.monocytogenes cell surface.
