A separate experiment was conducted to determine the optimal IPTG concentration and the frequency of At low concentration, IPTG enters cells through lactose permease, but at high concentrations (typically used for protein induction), IPTG can enter the cells independently of lactose permease. WikiMatrix At low IPTG concentrations (40 μM IPTG) the analogue behaviour was most pronounced with the DRLR covering a 245-fold range of PPDA concentration (Supplementary Table S2). As with the t T/ t system, both vertical and horizontal scaling of the PPDA dose response curves is observed, and additionally here the t T/ t T system allows the window of PPDA sensing to be greatly expanded or contracted. Followed that, with changing expression condition such as cell concentration before the induction, time period, temperature, shaking rate and inducer concentration (IPTG), rRMCP1 expression was optimized, and purified by Ni-NTA. The biological activity of the expressed protein was verified using monocyte migration assay. 이런 이유로 IPTG는 실험환경 내내 같은 농도로 유지된다. IPTG 유도(IPTG induction)을 하려면, 무균의 필터 여과한 1M 농도의 IPTG가 일반적으로 1:1000 희석 농도로 대수적(logarithmically)으로 성장중인 세균 배양액에 더해진다.

Prepare 1 ml LB + Antibiotic + 1mM IPTG in a 15 ml conical and prewarm to 37°C about 10 minutes before use. Note: IPTG concentration can vary from 0.1 to 1M. how much concentration of IPTG and its volume per litter will be use for protein induction. Kindly share the protocol for inducing protein through BL-21 for chitinase protein. View At low concentration, IPTG enters cells through lactose permease, but at high concentrations (typically used for protein induction), IPTG can enter the cells independently of lactose permease.
