Abstract excerpt
We have expressed the mature platelet-derived growth factor (PDGF) A chain within a fusion protein of the cro repressor and beta-galactosidase in Escherichia coli. Monomeric PDGF-A was excised from this fusion protein by CNBr cleavage. After protection of thiols by S-sulfonation, this fragment was purified by gel permeation chromatography and reversed-phase high-performance liquid chromatography. The monomeric...
