Purification of glycogen phosphorylase from small quantities of mouse skeletal muscle.

A new approach to the purification of skeletal muscle glycogen phosphorylase is described. The purification scheme is particularly suited to preparation of the enzyme from small amounts of tissue. A combination of dye-ligand chromatography and hydrophobic chromatography yields homogenous enzyme with good recoveries. The purification is rapid and may be completed in a working day.
