Human MEPE (Matrix Extracellular Phosphoglycoprotein) Microsample ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human MEPE. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human MEPE. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human MEPE, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human MEPE in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 0.32-20 ng/mL. Sensitivity: 0.137 ng/mL. Assay Type: Sandwich. Standard: 20 ng/mL. Sample Type: sSerum, plasma, tissue homogenates, cell lysates and other biological fluids. Assay duration: 3.5h. Protein Function: Promotes renal phosphate excretion and inhibits intestinal phosphate absorption (PubMed:14962809, PubMed:19005008). Promotes bone mineralization by osteoblasts and cartilage mineralization by chondrocytes (PubMed:18162525, PubMed:19998030, PubMed:22766095). Regulates the mineralization of the extracellular matrix of the craniofacial complex, such as teeth, bone and cartilage (By similarity). Promotes dental pulp stem cell proliferation and differentiation (PubMed:22341070) [The Uniprot Consortium]
