WebThe coding region for the sortase A (SrtA) of Staphylococcus aureus was fused at the N-terminus of LfcinB. The SrtA-LfcinB fusion protein in E. coli C43(DE3) was expressed with the expected sizes of 21 kDa and 38 kDa by pET21b-SrtA-LfcinB and pET32-1SrtA-LfcinB constructs, respectively. Increased levels of the TrxA-His-SrtA-SrtA-LfcinB fusion protein … WebSep 1, 2004 · However, it should be pointed out that even when toxicity existed in C41(DE3), the target protein were well overexpressed. For C41(DE3) and C43(DE3), respectively, 86 and 81% of the heterologous proteins from this study were expressed after 3 h of induction with IPTG at 37 °C. These percentages were higher than with BL21(DE3) in which only 54% ...
WebIPTG is added to a final concentration of 0.4 mM for induction of protein expression. Before the addition of IPTG, an aliquot of cell culture should be removed and incubated separately as an uninduced control (sample 1, uninduced). Initially induction at 37°C for 2-4 hours can be tested for expression and solubility. WebThe first step in protein purification is to express the protein in a cellular host. In our case we will be using E. coli. The pET28-His6-GFP construct we made contains an IPTG-inducible His6-GFP. Once the cells start growing, we will “induce” them …
