Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate DLK2 in samples. An antibody specific for DLK2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDLK2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DLK2 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 DLK2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:The Dlk1 gene appears to function as a regulator of adipogenesis. Adult Dlk1-deficient mice are obese, but adipose tissue still develops in transgenic mice overexpressing an Fc-dlk1 fusion protein, and neither type of genetically modified mice displays serious abnormalities. EGFL9, encoding for a protein whose structural features are virtually identical to those of dlk1, suggesting it may function in a similar way. As dlk1 does, the protein encoded by EGFL9/Dlk2 affects adipogenesis of 3T3-L1 preadipocytes and mesenchymal C3H10T1/2 cells; however, it does so in an opposite way to that of dlk1. In addition, expression levels of both genes appear to be inversely correlated in both cell lines. Moreover, enforced changes in the expression of one gene affect the expression levels of the other.
