Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate LCE3B in samples. An antibody specific for LCE3B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLCE3B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LCE3B 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 LCE3B bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:By database analysis to identify human orthologs of mouse genes encoding late envelope proteins (LEPs), Marshall et al. (2001) identified LCE3B, which they called LEP14. RT-PCR detected strong LEP14 expression in human esophagus, but not in skin or heart.Using real-time PCR, Jackson et al. (2005) detected little to no LCE3B expression in human skin or internal epithelia.
Jackson et al. (2005) determined that the LCE3B gene contains 2 exons. Exon 1 is noncoding.By genomic sequence analysis, Marshall et al. (2001) mapped the LCE3B gene within the LCE gene cluster on chromosome 1q21. Jackson et al. (2005) stated that the mouse Lce3b gene maps to a syntenic LCE gene cluster on chromosome 3F1.
