Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate DMP1 in samples. An antibody specific for DMP1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDMP1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DMP1 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 DMP1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:DMP1 is critical for proper mineralization of bone and dentin, is present in diverse cells of bone and tooth tissues. The protein contains a large number of acidic domains, multiple phosphorylation sites, a functional arg-gly-asp cell attachment sequence, and a DNA binding domain. In undifferentiated osteoblasts it is primarily a nuclear protein that regulates the expression of osteoblast-specific genes. During osteoblast maturation the protein becomes phosphorylated and is exported to the extracellular matrix, where it orchestrates mineralized matrix formation. Mutations in the gene are known to cause autosomal recessive hypophosphatemia, a disease that manifests as rickets and osteomalacia. The gene structure is conserved in mammals. Two transcript variants encoding different isoforms have been described for this gene.
