Principle of the Assay: AGC ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for AGC. Standards or samples are then added to the microtiter plate wells and AGC if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of AGC present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for AGC are added to each well to "sandwich" the AGC immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, substrate solutions are added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain AGC and enzyme-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The AGC concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
an extracellular matrix proteoglycan; cleaved by ADAMTS1 [RGD, Feb 2006]
Uniprot Description
This proteoglycan is a major component of extracellular matrix of cartilagenous tissues. A major function of this protein is to resist compression in cartilage. It binds avidly to hyaluronic acid via an N-terminal globular region. May play a regulatory role in the matrix assembly of the cartilage.
