Description:

Myoglobin (Mb) is a monomeric 17,800-Da protein, which incorporates a heme group in a hydrophobic crevice during the folding process.It can transport and store oxygen in muscles. Mb is present in oxidative striated muscles and cardiac myocytes as well as in smooth muscle cells. Notably, Mb has also been traced in human tumor-associated mammary cells. Mb can be detected in the serum as early as two hours after myocardial necrosis begins. Mb has low cardiac specificity but high sensitivity, which makes it most useful for ruling out myocardial infarction if the level is normal in the first four to eight hours after the onset of symptoms.
