| Hazard Information | Back Directory | [Definition]
A globular protein occurringwidely in muscle tissue as anoxygen carrier. It comprises a singlepolypeptide chain and a haem group, which reversibly binds a moleculeof oxygen. This is only relinquishedat relatively low externaloxygen concentrations, e.g. duringstrenuous exercise when muscle oxygendemand outpaces supply fromthe blood. Myoglobin thus acts as anemergency oxygen store. | [Purification Methods]
Myoglobin is purified by CM-cellulose chromatography and Sephadex G-50 followed by chromatography on Amberlite IRC-50 Type III or BioRex 70 (<400mesh). The crystalline product as a paste in saturated (NH4)2SO4 at pH 6.5-7.0 may be stored at 4o for at least 4years unchanged, but must not be kept in a freezer.
