Vitellogenin ELISA kits are assays designed to measure levels of vitellogenin-related antigens in biological samples, such as plasma, serum, culture extracts, and cell lysates. Vitellogenin is a protein found in many species, including chicken, fruit fly and C. elegans. It is a precursor of egg yolks and is naturally expressed in the females of egg-laying species. Expression of this protein in male animals has been used as biomarker for estrogenic endocrine disruptive chemicals (EDCs).Some human proteins, such as MTTP and APOB, contain a vitellogenin domain. Vitellogenin ELISA kits utilize microtiter plates coated with specific antibodies and conjugated detection enzymes. The assay will produce a detectable signal proportional to the amount of Vitellogenin antigens found in the sample.
