COMP Chemi-Luminescent ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Cartilage Oligomeric Matrix Protein (COMP) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Cartilage Oligomeric Matrix Protein (COMP) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Cartilage oligomeric matrix protein; cartilage oligomeric matrix protein (pseudoachondroplasia, epiphyseal dysplasia 1, multiple) ; CTS2; EDM1; EPD1; MED; PSACH; pseudoachondroplasia (epiphyseal dysplasia 1, multiple) ; THBS5; thrombospondin-5; TSP5.

May play 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) . 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 (By similarity) .

The microplate provided in this kit has been pre-coated with an antibody specific to Cartilage Oligomeric Matrix Protein (COMP) . Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Cartilage Oligomeric Matrix Protein (COMP) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Cartilage Oligomeric Matrix Protein (COMP) level in the sample or standard.
