Optimization of secretory expression of recombinant hGM-CSF in high cell density cultivation of recombinant Escherichia coli using Taguchi statistical method

Authors: not saved
Abstract:

Human granulocyte macrophage colony stimulating factor (hGM-CSF) has many therapeutic applications.In this study, in order to verify the purification process, the effect of carbon source, IPTG concentration andpost-induction time on the secretion of recombinant hGM-CSF into the culture medium by recombinantEscherichia coli during high cell density cultivation were evaluated by using the Taguchi statistical method. The results indicated that glucose, 1mM IPTG and a time of 6 h post-induction, represented optimum conditions. The secreted hGM-CSF, overall volumetric productivity and purified hGM-CSF were 373 mg/l, 18 mg/l/h and 63 mg/l, respectively.

Enhanced Expression of Recombinant Activin A in Escherichia coli by Optimization of Induction Parameters

Activin A is a member of the transforming growth factor β super family. Because of its extensive clinical usages, its recombinant production is beneficial. In this study, activin A was expressed in E. coli using the pET 21a expression vector. The optimization of the activin A production in E. coli was done by using the response surface methodology (RSM). At this stage, the effect of IPTG and la...

Optimization of Cloning Conditions for high-level Production of Recombinant Mouse Interleukin-2 in Escherichia coli

Backgrounds and objectives: Interleukin 2 (IL-2) secreted by activated CD4+ T cells  has been known as a major mediator in both  adaptive and native immune system  due to a board range of effects on  different cells in the immunity system (1-6). Methods: cDNA synthesis was performed using gene- specific primers designed by Gene Runner software after RNA extraction of mouse splenocytes. PCR pro...

Framework for online optimization of recombinant protein expression in high-cell-density Escherichia coli cultures using GFP-fusion monitoring.

A framework for the online optimization of protein induction using green fluorescent protein (GFP)-monitoring technology was developed for high-cell-density cultivation of Escherichia coli. A simple and unstructured mathematical model was developed that described well the dynamics of cloned chloramphenicol acetyltransferase (CAT) production in E. coli JM105 was developed. A sequential quadratic...
