Description_x000D_ General description_x000D_ Myoglobin is a heme-related, low-molecular-weight protein. It is mainly found in cardiac and skeletal muscle._x000D_ Application_x000D_ Myoglobin from human heart has been used as a negative control in monitoring isoAsp formation during storage. It has also been used as an antigen in the study to identify self-antigens recognized by serum autoantibodies from unimmunized mice strains._x000D_ Myoglobin from human heart was used to study the interactions of a platinum (II) 9-aminoacridine complex with proteins and oligonucleotides by ESI-TOF MS. It was also used in the evaluation of plasma myoglobin using the Stratus CS fluorometer._x000D_ Biochem/physiol Actions_x000D_ Myoglobin may help to increase diffusion and also stores O2 in oxidative muscle. It can momentarily act as an oxygen reservoir to supply oxygen when there is inadequate blood oxygen delivery at the time of intense muscular activity._x000D_ Physical form_x000D_ Solution in 20 mM Tris-HCl, 1 mM EDTA and 50% glycerol, pH 8.5, 2 mg protein per mL (Lowry)
