Designing recombinant Escherichia coli strain for expression of Interleukin-3 and Interleukin-11 in fusion form with PELB

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...

Advances and challenges in recombinant protein expression in Escherichia coli

Recombinant Production of Human Interleukin 6 in Escherichia coli

In this study, we compared basic expression approaches for the efficient expression of bioactive recombinant human interleukin-6 (IL6), as an example for a difficult-to-express protein. We tested these approaches in a laboratory scale in order to pioneer the commercial production of this protein in Escherichia coli (E. coli). Among the various strategies, which were tested under Research and De...

Bacterial Overexpression of the Human Interleukin-2 in Insoluble Form via the pET Trx Fusion System

Selection of a system for successful recombinant protein production is important. The aim of this study wasto produce high levels of human interleukin-2 (hIL-2) in soluble form. To this end, the pET32a vector inEscherichia coli BL21 (DE3) was used as an expression system, since it was previously used for the productionof mouse IL-2 in soluble form. The results indicated that c...

Cloning and Expression of Recombinant Human Interleukin-7 in Chinese Hamster Ovary (CHO) Cells

Background: The critical role of interleukin-7 (IL-7) in homeostatic proliferation and T cell survival has made it a promising cytokine for the treatment of various clinical conditions, especially those associated with lymphopenia. Methods: In the present study we expressed recombinant human interleukin-7 (rhIL-7) in Chinese hamster ovary (CHO)-K1 cells. CHO-K1 cells were stably transfected ...
