Description
Monoclonal antibodies (MAbs) were produced against sailfish (Istiophorus platypterus) albumin and investigated for their potential use in species identification. Balb/c mice were immunized with albumin purified from sailfish serum. Hybridomas were screened by enzyme-linked immunosorbent assay (ELISA) for reactivity with the purified albumins of sailfish, blue marlin (Makaira nigricans) and white marlin (Tetrapturus albidus). MAbs from 18 different hybridomas exhibited activity against sailfish albumin. Sixteen MAbs showed cross-reactivity with the marlin species. Two MAbs displayed distinct specificity for sailfish albumin. One of these MAbs (M2D1) was conjugated to horseradish peroxidase to construct an ELISA for the identification of sailfish from serum. The assay correctly identified 18 sailfish from 36 billfish samples. The MAb-peroxidase conjugate was highly specific toward sailfish with no detectable reaction against the heterologous species.
