Inical effects of glycosylated and nonglycosylated hGCSF on chemotherapy-induced neutropenia were not drastically unique statistically within a clinical trial. eight Soluble Overexpression and Purification of hGCSF Conclusion This study demonstrates that fusion proteins in addition to a low expression temperature might be applied to effectively express soluble hGCSF in the cytoplasm of E. coli. Working with uncomplicated chromatographic procedures and TEV protease digestion,.ten mg of hugely bioactive hGCSF was purified from 500 mL cultures of cells expressing Autophagy MBP-hGCSF or PDIb’a’-hGCSF. either 18uC or 30uC. Immediately after 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 just before IPTG induction; T, total protein following IPTG induction; P, protein in the cell pellet just after sonication; S, protein inside the supernatant after sonication.
