purpose: in order to express human granulocyte-macrophage colony stimulating factor (hgm-csf) under heat shock. materials and methods: two expression plasmids were constructed based on pbc(sk) plasmid. the expression cassettes in the two plasmids are equipped with a 75 base pair fragment, derived from the pl promoter of the bacteriophage lambda (λ). the plasmids also contain a temperature muta...

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,...

MANA OLOOMI, SAEID BOUZARI,

Bacterial expression systems provide economic and logistic advantages in manufacturing proteins for human therapeutic purposes. However, most such proteins accumulate in insoluble biologicaIIy inactive form when overexpressed in bacterial cells. This is the case while attempting to produce recombinant human granulocyte-macrophage colony stimulating factor (hGM-CSF) in E. coli. In this repor...

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 ...
