The TecoMedical Ultra sensitive Salmonid Vitellogenin ELISA shows despite relatively short immune incubation times of total 180 minutes a very high sensitivity. The linear standard range between 0.012 ng/ml and 1 ng/ml with mean intra-assay and inter-assay CVs of 4.4% and 8.0% respectively allow an accurate measurement of vitellogenin above 0.012 ng/ml in different salmonid species.

In non-treated juvenile rainbow trouts no concentration above the detection limit of 0.002 ng/ml was detected. However within 3 days after exposure to E2 a measureable change in vitellogenin concentrations was observed and thus the proof of vitellogenin in salmonid mucus in trace amounts reflects a reliable biomarker for the exposure to exogeneous estrogens.
