N2 - In this study, we characterized proteinase A secreted by recombinant Saccharomyces cerevisiae bearing a multicopy plasmid containing the encoding gene (PEP4). Polyclonal and monoclonal antibodies were raised to study the product heterogeneity. Characterization of proteinase A was performed by immunoelectrophoresis and immunoblotting techniques. None of the monoclonal antibodies raised against proteinase A was found to react with the glycosyl side chains; thus cross-reaction with other glycosylated proteins (e.g. carboxypeptidase Y) was very low. This study allowed us to develop an ELISA method for the quantification of proteinase A in culture supernatants as well as the evaluation of monoclonal antibodies for their use in immunoaffinity chromatography.
