Webovernight and were grown up to an OD 600 of 0.4 and put on ice. Plasmids pMAL-c2X and pMAL-c2X-LLMZ16 were provided from the Eltis lab and Lapointe et al., ... mM IPTG) and induction time (1 hour vs 2 hour). 2 mL aliquots of each culture were saved for analysis by SDS-PAGE. The aliquots WebInfobox references. Isopropyl β-d-1-thiogalactopyranoside ( IPTG) is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator . imx stacey

WebStrain TB741, with a phoA reporter fused to the Para promoter, was transformed with the indicated plasmids and grown overnight with 50 µM IPTG and 0.4% glucose or 0.1% arabinose. WebThe overnight culture was normalized to ~1 × 10 9 cells mL −1 with the pre-warmed S7 medium, supplemented with 0.005% Xyl and split. Amp (3 μg mL −1), IPTG (2 mM), or both Amp and IPTG were added and the cells incubated up to 240 min. At the indicated times, IPTG, Amp, or both were removed from the medium and the culture was plated on LB ... WebIncubate at 37°C until OD 600 reaches 0.4–0.8. Induce with 4 or 40 µl of a 100 mM stock of IPTG (final concentration of 40 or 400 µM) and induce for 3 to 5 hours at 37°C. Check for expression either by Coomassie stained protein gel, Western Blot or activity assay. imx secure boot
