کلونینگ و بیان پروتئین M2 ویروس آنفلوانزا H1N1 در باکتری Ecoli سویه BL21(DE3)
سابقه و هدف: ویروس انفلوانزا A یکی از عوامل اصلی مرگ ومیر سالیانه می باشد و از سال 1960 میلادی بر علیه آن واکسن موثر در دسترس بوده است. تغییرات مداوم آنتی ژنیک ویروس چالش بزرگی در مسیر تولید سالیانه واکسن می باشد. در حال حاضر محققین روی آنتی ژنهای ثابت ویروس مطالعه می کنند. پروتئینM2 یک کانال یونی درون پوشش ویروس انفلوانزای A تشکیل می دهد که در عفونت زایی آن موثر است. این پروتئین حفاظت شده ا...
متن کاملThe toxicity of recombinant proteins in Escherichia coli: a comparison of overexpression in BL21(DE3), C41(DE3), and C43(DE3).
Two mutant strains of Escherichia coli BL21(DE3), called C41(DE3) and C43(DE3) and originally described by Miroux and Walker, are frequently used to overcome the toxicity associated with overexpressing recombinant proteins using the bacteriophage T7 RNA polymerase expression system. Even when the toxicity of the plasmids is so high that it prevents transformation in the strain BL21(DE3), the to...
متن کاملGenomic and transcriptomic landscape of Escherichia coli BL21(DE3)
Escherichia coli BL21(DE3) has long served as a model organism for scientific research, as well as a workhorse for biotechnology. Here we present the most current genome annotation of E. coli BL21(DE3) based on the transcriptome structure of the strain that was determined for the first time. The genome was annotated using multiple automated pipelines and compared to the current genome annotatio...
متن کاملComplete Genome Sequence of Escherichia coli BLR(DE3), a recA-Deficient Derivative of E. coli BL21(DE3)
Escherichia coli BLR(DE3) is a commercially available recA-deficient derivative of BL21(DE3), one of the most widely used strains for recombinant protein expression. Here, we present the full-genome sequence of BLR(DE3) and highlight additional differences with its parent strain BL21(DE3) which were previously unreported but may affect its physiology.
متن کاملHigh-level production of membrane proteins in E. coli BL21(DE3) by omitting the inducer IPTG
BACKGROUND For membrane protein production, the Escherichia coli T7 RNA polymerase (T7 RNAP)-based protein production strain BL21(DE3) in combination with T7-promoter based expression vectors is widely used. Cells are routinely cultured in Lysogeny broth (LB medium) and expression of the chromosomally localized t7rnap gene is governed by the isopropyl-β-D-1-thiogalactopyranoside (IPTG) inducibl...
