Rat COMP(Cartilage Oligomeric Matrix Protein) ELISA Kit

Plays a role in the structural integrity of cartilage via its interaction with other extracellular matrix proteins such as the collagens and fibronectin. Can mediate the interaction of chondrocytes with the cartilage extracellular matrix through interaction with cell surface integrin receptors. Could play a role in the pathogenesis of osteoarthritis. Potent suppressor of apoptosis in both primary chondrocytes and transformed cells. Suppresses apoptosis by blocking the activation of caspase-3 and by inducing the IAP family of survival proteins (BIRC3, BIRC2, BIRC5 and XIAP) (By similarity). Essential for maintaining a vascular smooth muscle cells (VSMCs) contractile/differentiated phenotype under physiological and pathological stimuli. Maintains this phenotype of VSMCs by interacting with ITGA7 (PubMed:20019333) Assay Type: Sandwich. Sensitivity: 0.97 ng/mL. Standard: 200 ng/mL. Detection range: 3.13-200 ng/mL. Sample type: serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids. Assay length: 3.5h. Research Field: Metabolic pathway,Bone metabolism,. Test principle: 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 Rat COMP. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat COMP. 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 Rat COMP, 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 Rat COMP in the samples is then determined by comparing the OD of the samples to the standard curve.
