Abstract
Two female-specific serum proteins (FSSPs) were detected immunologically in estradiol-treated Japanese sardine Sardinops melanostictus. The major FSSP was demonstrated to be a high molecular estradiol-inducible glycolipophosphoprotein with an immunological relation to a major yolk protein, and was suggested to be vitellogenin (VTG). VTG was purified using negative immunoaffinity chromatography. The isolated VTG was used for raising the specific antiserum against VTG. A homologous enzyme-linked immunosorbent assay (ELISA) was developed using the antiserum and the isolated VTG. The sensitivity range of the ELISA was 44 ng/ml to 2670 ng/ml of VTG concentration for the conditions used in our investigation.
