Inical effects of glycosylated and nonglycosylated hGCSF on chemotherapy-induced neutropenia were not significantly unique statistically in a clinical trial. eight Soluble Overexpression and Purification of hGCSF Conclusion This study demonstrates that fusion proteins as well as a low expression temperature could be made use of to successfully express soluble hGCSF inside the cytoplasm of E. coli. Employing very simple chromatographic procedures and TEV protease digestion,.10 mg of very bioactive hGCSF was Tubastatin-A purified from 500 mL cultures of cells expressing MBP-hGCSF or PDIb’a’-hGCSF. either 18uC or 30uC. Following sonication, 20 mg of each total protein was loaded onto a 10% Tris-tricine gel. The arrows indicate the hGCSF fusion proteins. M, molecular weight size marker; C, total protein ahead of IPTG induction; T, total protein following IPTG induction; P, protein within the cell pellet immediately after sonication; S, protein in the supernatant just after sonication.
