one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
Background: Pseudomonas protein expression in E. coli is known to be a setback due to signifi cant genetic variation and absence of several genetic elements in E. coli for regulation and activation of Pseudomonas proteins. Modifi cations in promoter/repressor system and shuttle plasmid maintenance have made the expression of stable and active Pseudomonas protein possible in bot...
Background: Pivotal roles of Nerve growth factor (NGF) in the development and survival of both neuronal and non-neuronal cells indicate its potential for the treatment of neurodegenerative diseases. However, investigation of NGF deficits in different diseases requires the availability of properly folded human b-NGF. In previous studies bacterial expression of hNGF demonstrated the feasibility o...
Background: Escherichia coli is still the common host for ing and heterologous protein expression. Various strategies have been employed to increase protein expression in E. coli, but, it seems that external factors such as selection marker concentration can drastically aff ect the yield of protein and plasmid.Objectives: Alterations of protein expression...
for high-throughput production of recombinant protein in escherichia coli ( e. coli ), besides important parameters such as efficient vector with strong promoter and compatible host, other important issues including codon usage, rare codons, and gc content specially at n-terminal region should be considered. in the current study, the effect of decreasing the percentage of gc nucleotides and opt...
background and objectives: baculovirus can be used as a vector in gene delivery system. viral envelope of baculovirus would display expressed protein/peptide and it could render as a potential vaccine delivery system. in this regard, the gene coding for a subunit of shiga toxin (stxa) from escherichia coli ( e. coli ) strain was cloned in a baculovirus expression system. stxa subunit has the ab...
objectives: in present study we aimed to clone the lux i gene encoding n-acyl-homoserine synthase detected in biofilm forming clinical isolates of acinetobacter baumannii and study its expression in escherichia coli transformants. materials and methods: four a. baumannii hospital strains which demonstrated strong biofilm activity were selected in this investigation. the presence of lux i gene w...
In this study, our previously reported novel synthetic gene encoding 166 residues of interferon-? was used for an efficient expression of IFN-?. The synthetic gene was cloned into pET21a expression vector and transferred into E. coli. Recombinant protein was over-expressed in the E. coli. Identity of the recombinant protein was confirmed by western blot analysis. The recombinant protein was bio...
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 ...
