Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate DNMT3B in samples. An antibody specific for DNMT3B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDNMT3B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DNMT3B 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 DNMT3B bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:DNMT3B, is a protein associated with immunodeficiency, centromere instability and facial anomalies syndrome. CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase which is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes primarily to the nucleus and its expression is developmentally regulated. Mutations in this gene cause the immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome. Six alternatively spliced transcript variants have been described. The full length sequences of variants 4 and 5 have not been determined.
