Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate DMRT1 in samples. An antibody specific for DMRT1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDMRT1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DMRT1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of DMRT1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:DMRT1 is found in a cluster with two other members of the gene family, having in common a zinc finger-like DNA-binding motif (DM domain). The DM domain is an ancient, conserved component of the vertebrate sex-determining pathway that is also a key regulator of male development in flies and nematodes, and is found to be the key sex-determining factor in chickens. This gene exhibits a gonad-specific and sexually dimorphic expression pattern, just like the related doublesex gene in fruit flies. The protein contains a nuclear localization signal between the 2 zinc-binding sites of the DM domain, which is located in the N terminus. Immunohistochemical analysis of adult human testis revealed that DMRT1 localized to nuclei of Sertoli cells, spermatogonia, and spermatocytes.
