Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate WNT3 in samples. An antibody specific for WNT3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyWNT3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for WNT3 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 WNT3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:The WNT gene family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. WNT3 is a member of the WNT gene family. It encodes a protein which shows 98% amino acid identity to mouse Wnt3 protein, and 84% to human WNT3A protein, another WNT gene product. The mouse studies show the requirement of Wnt3 in primary axis formation in the mouse. Studies of the gene expression suggest that this gene may play a key role in some cases of human breast, rectal, lung, and gastric cancer through activation of the WNT-beta-catenin-TCF signaling pathway. This gene is clustered with WNT15, another family member, in the chromosome 17q21 region.
