Principle of the Assay||Myoglobin ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-Myoglobin antibody and an Myoglobin-HRP conjugate. The assay sample and buffer are incubated together with Myoglobin-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the Myoglobin concentration since Myoglobin from samples and Myoglobin-HRP conjugate compete for the anti-Myoglobin antibody binding site. Since the number of sites is limited, as more sites are occupied by Myoglobin from the sample, fewer sites are left to bind Myoglobin-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Myoglobin concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the globin superfamily and is expressed in skeletal and cardiac muscles. The encoded protein is a haemoprotein contributing to intracellular oxygen storage and transcellular facilitated diffusion of oxygen. At least three alternatively spliced transcript variants encoding the same protein have been reported. [provided by RefSeq, Jul 2008]
