Abstract

See full text

Methods for improving purification and quantification of platelet derived growth factor (PDGF) proteins having structural heterogeneity are provided. Preparation of substantially pure isoforms of these proteins is achieved using TSK sulfopropyl cation exchange chromatography and reverse phase high performance liquid chromatography. A reverse charged capillary zone electrophoresis method enables quantification of substantially pure isoforms of these proteins resulting from endoproteolytic post-translational modifications. Compositions of the invention are substantially purified isoforms of secreted PDGF proteins having structural heterogeneity, more particularly purified intact, single-clipped, and double-clipped isoforms of recombinant PDGF-BB. Pharmaceutical compositions comprising at least one of these substantially purified recombinant PDGF isoforms and methods for their use in promoting wound healing are also provided.
