Background: interleukin-2 (IL-2) is a protein consisted of 132 amino acids (MW = 1.53 kDa). Aldesleukin is the synthetic form of the protein which is used as an effective function for immuno system. Current study was aimed to investigate the expression of rhIL-2 in E. coli BL21 (DE3) expression system in order to produce an active recombinant form of the protein. Methods: Firstly codon optimization was done for hIL-2 gene. Then the gene was synthesized and inserted in pET-22a vector by a ...
Several expression hosts have been employed for the production of bone morphogenetic protein2 (BMP- 2), inducing de novo bone formation and is widely used in clinical applications. However,every expression system has its merits and demerits. For example, although Escherichia coli issimple and robust, but inept to make disulfide bond; hence, heterologous proteins are produced inthe form of inclusion bodies, entailing in vitro refolding strategies. On the other hand, yeast, whichis a lower ...
