Mouse Myoglobin ELISA

Myoglobin is a single-chain globular protein containing a heme group in the center. Myoglobin is found in both cardiac and skeletal muscle tissues. It is released from damaged muscle tissues and therefore makes it a sensitive marker for muscle injury.

In this assay the Myoglobin present in samples reacts with the anti-Myoglobin antibodies which have been adsorbed to the surface of polystyrene microtiter wells. After the removal of unbound proteins by washing, antiMyoglobin antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound Myoglobin. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3’,5,5’- tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of Myoglobin in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of Myoglobin in the test sample. The quantity of Myoglobin in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution.
