Abstract
In this study, a specific monoclonal antibody againstListeria monocytogenes was screened using an SPR biosensor Monoclonal antibodies were bound to protein L, after which theL. monocytogenes cells were subjected to an affinity assay. Protein L was immobilized on a carboxymethyl dextran (CM-Dex) surface via an amine coupling method and utilized repeatedly by regeneration. The monoclonal antibody, ‘A18’, was selected and employed for the high-sensitivity detection ofL. monocytogenes. Under optimized conditions, 103 cells/ml or 50 cells were detected by the SPR biosensor.
