Effect of specific growth rate on the production of a recombinant nuclease by Escherichia coli

Efficient Process Development of Recombinant Human Granulocyte Colony-Stimulating Factor (rh-GCSF) Production in Escherichia coli

Background: The protein hormone granulocyte colony-stimulating factor (GCSF) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. Methods: An efficient process was developed for heterologous expression of human GCSF in E. coli BL21 (DE3). The feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...

Fed-batch Cultivation of Recombinant Escherichia coli Producing Human Interferon-γ Under Controlled Specific Growth Rate

The Effect of Heat Shock on Production of Recombinant Human Interferon Alpha 2a (rhIFN α -2a) by Escherichia coli

Recombinant human interferon alpha 2a (rhIFN α -2a) production and cell growth were monitored in a set of genetically modified E. coli strains (MSD1519, MSD1520, MSD 1521, MSD 1522, MSD 1523) producing rhIFN α -2a. The growth was followed at OD 600 nm, changes in cell physiology were detected by pyrolysis mass spectrometry (PyMS) of cell biomass and recombinant protein production was determined...

Stability of Recombinant Proteins in Escherichia coli: The Effect of Co-Expression of Five Different Chaperone Sets

Chaperones are produced by prokaryotic, yeast and higher eukaryotic cells for various purposes. Over-expression of each chaperone or sets of them affect the production level of a recombinant protein in the cell. On the basis of this hypothesis, five different plasmids with 5 different combinations of 6 chaperones molecule, transformed into Escherichia coli along with human basic Fibroblast Grow...
