recombinant protein production in e. coli has several advantages over other expression systems. misfolding, inclusion body formation, and lack of eukaryotic post translational modification are the most disadvantages of this system. exporting of correctly folded proteins to the outside of reductive cytoplasmic environment through twin-arginine system could help to pass these limiting steps. two ...

the aim of current study was to investigate the nucleotide sequence of seven trna genes in mitochondrial gene of khorasan’s native chicken and identification of possible mutations in it. for performing it, this part of the gene was cloned using the specific amplification initiators and cloned in the plasmid ptg19-t vector in dh5α strain of e-coli after the sampling and extracting the dna from w...

For any lacunary sequence $theta = (k_{r})$, we define the concepts of $S_{theta}-$limit point and $S_{theta}-$cluster point of a sequence of fuzzy numbers $X = (X_{k})$. We introduce the new sets  $Lambda^{F}_{S_{theta}}(X)$, $Gamma^{F}_{S_{theta}}(X)$ and prove some inclusion relaions between these and the sets $Lambda^{F}_{S}(X)$, $Gamma^{F}_{S}(X)$ introduced in ~cite{Ayt:Slpsfn} by Aytar [...
