说明书:

Detection of egg yolk protein vitellogenin (Vtg) in juvenile and male fish is a simple and sensitive biomarker for endocrine disrupting chemicals (EDCs) with estrogenic effects in fish. Measuring Vtg has become accepted as a routine screening test for estrogenic effects of EDCs in fish. This quantitative Vtg Enzyme-Linked Immunosorbent Assay (ELISA) can easily be combined with standard fish tests according to OECD Guidelines for Testing of Chemicals

The quantitative Rainbow trout Vtg ELISA Kit is developed for a standard OECD test species used in many ecotoxicological testing laboratories throughout the world, the rainbow trout (Oncorhynchus mykiss). The assay is optimised for analysis of blood plasma samples, but can also be used for other sample types (e.g. hepatocyte culture supernant)

The analysis is based on a sandwich assay utilizing specific binding between antibodies and Vtg. Microtiter plates are pre-coated with a Vtg-specific capture antibody, which binds to Vtg in samples added to the wells. Unbound components are washed out, and a second Vtg-specific antibody (detecting antibody) labelled with the enzyme acetylcholinesterase (AChE) is added, creating a sandwich of antibodies and Vtg. After a last wash, the enzyme activity is determined by adding a substrate which gives a coloured product. The enzyme activity (colour intensity) is directly proportional to the concentration of Vtg in the sample, and the assay is calibrated using purified Vtg from rainbow trout as standard.

The assay is highly sensitive and robust. The working range of the Vtg standard is normally 1.6-50 ng Vtg/ml and the intra- and inter-assay coefficients of variation (%CV) are between 2.4 and 11% within the working range.

The kit contains pre-coated microtiter plates, rainbow trout Vtg standard, antibodies and reagents necessary for running the assay, as well as an instructive protocol.
