Abstract

A process is described for producing M-CSF from bacteria. It includes: fermentation of bacteria containing M-CSF DNA; harvest of the fractions that contain the M-CSF protein (refractile bodies); primary recovery of the protein; solubilization and denaturation of refractile bodies; M-CSF refolding; purification by column chromatography and other methods; and formulation of the properly refolded M-CSF. This method is advantageous over prior methods in terms of yield and purity.
