ABSTRACT: Four monoclonal antibodies (MAbs) directed to native glycerophospholipid:cholesterol acyltransferase (GCAT) epitopes of Aeromonas salmonicida were isolated using an esterase capture assay. The molecular mass of this MAb-defined antigen was estimated to be 26 kDa in SDS-PAGE. Three different epitope specificities of these MAbs were demonstrated. It was shown that all 4 MAbs recognize GCAT in culture filtrates of the strain MT004 excluding the simultaneous trapping of other components. None of the MAbs react with the denatured GCAT in Western blots.
