A polypeptide growth factor has been partially purified from medium conditioned by the human adrenocortical carcinoma cell line SW13. This factor, designated h-TGFe, stimulates anchorage-independent growth of the SW13 cells. Similar activity was observed in human milk, and in conditioned media from

β¦ Synopsis
Human recombinant EGF, secreted into the extracellular medium by E. c&i cells, was purified by a combination of solid phase extraction and HPLC. Using these techniques, the peptide was purified 122-fold, with a recovery of greater than 75%. The purified hEGF manifested no contaminating protein bands on electrophoretic gels. Amino acid analysis of the purified peptide was identical to that of authentic hEGF.
