Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate DLL3 in samples. An antibody specific for DLL3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDLL3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DLL3 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 DLL3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:DLL3 encodes a member of the delta protein ligand family. This family functions as Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. Mutations in this gene cause autosomal recessive spondylocostal dysostosis 1. Two transcript variants encoding distinct isoforms have been identified for this gene.
In humans, the fact that mutations in genes required for oscillation, such as DLL3, result in abnormal segmentation of the vertebral column suggests that the segmentation clock also acts during human embryonic development. Disruption of the Notch pathway occurs in Alagille syndrome , a disorder that has vertebral abnormalities, i.e., 'butterfly vertebrae,' as a feature in about two-thirds of patients.
