چکیده

fusion of two genes at dna level produces a single protein, known as a chimeric protein. immunotoxins are chimeric proteins composed of specific cell targeting and cell killing moieties. bacterial or plant toxins are commonly used as the killing moieties of the chimeric immunotoxins. in this investigation, the catalytic domain of shiga-like toxin (a1) was fused to human granulocyte macrophage colony stimulating factor (hgm-csf) gene and the fused gene was then expressed using an expression vector containing arabinose promoter. the protein thus obtained could be recognized by two different elisa system designed for detection of hgm-csf and shiga-toxin and reconfirmed by western-blot. the recognition of the chimeric protein by specific antibodies could be indicative of the proper form of the protein, which justifies further steps to be taken to evaluate the potential effects of the chimeric protein. iran. biomed. j. 9 (4): 143-148, 2005

The Expression of Human Granulocyte Macrophage Colony Stimulating Factor by Heat-Induction in Escherichia coli

A self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pL promoter, was constructed. The designed 5024 base pair expression plasmid contained a heat sensitive repressor cI857 coding gene to regulate the function of ?pL promoter under heat shock induction. Using the constructed vector,...

With the aim of the secretion of human granulocyte macrophage-colony stimulating factor (hGM-CSF) in Escherichia coli, hGM-CSF cDNA was fused in-frame next to the signal sequence of ST toxin (ST-I) of exteroxigenic E. coli, containing 53 or 19 amino acids of signal peptide. The fused STsig::hGM-CSF coding fragments were inserted into a T7-based expression plasmid. The recombinant plasmids were ...
