About This Kit
The Human Sclerostin (SOST) ELISA quantitates Hu Sclerostin human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu Sclerostin.
Principle of the method
The Human Sclerostin solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Rigorous validation
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.
Target information
Sclerostin, a glycoprotein predominantly secreted by osteocytes, is a member of the Cerberus/DAN family of putative BMP antagonists that functions as an endogenous regulator of the canonical Wnt signaling pathway and an inhibitory regulator of bone homeostasis. Although expressed nearly exclusively by osteocytes, sclerostin can also be found at significant levels elsewhere, such as bone, bone marrow, cartilage, the kidney, and the liver, and has also been shown to be produced by hypertrophic chondrocytes and cementocytes. Like DKK family members DKK-1 and DKK-4, sclerostin plays an important regulatory role in the Wnt/beta-catenin signaling pathway by forming inhibitory complexes with LDL Receptor-related proteins 5 and 6 (LRP5 and LRP6), which are essential components of the Wnt/beta-catenin signaling system. LRP5 and LRP6 are single-pass transmembrane proteins that appear to act as co-receptors for Wnt ligands involved in the Wnt/beta-catenin signaling cascade. Sclerostin has also been shown to interact directly with LRP4 via its extracellular domain to facilitate inhibition of Wnt signaling, and can catabolically promote osteoclast activity by increasing osteocyte expression of RANKL. Sclerostin's critical involvement in the regulation of bone formation and resorption is emphasized by two bone dysplasia disorders, sclerosteosis and van Buchem disease (VBD), caused by rare autosomal recessive mutations that result in progressive bone overgrowth and hypermineralization due to markedly decreased sclerostin levels.
