WebIPTG concentration for induction is around 0.5-1 mM. How do I make IPTG 0.1 M concentration solution in 50 mL? Dissolve 0.595 g IPTG (MW = 238.3 g/mol) in water. Adjust final volume to 25 mL with sterile water. Make 1 mL or 5 mL aliquots and sterilize by 0.22 µm filtration and store at 20°C. WebIn contrast, increasing IPTG concentration caused a decrease in overall RFP expression. This decrease in RFP expression was most likely due to plateauing bacterial growth. Figure 2. OD600 kinetic trace. OD600 readings were recorded every 10 minutes over the course of 24 hours (n=3). As IPTG concentration increased, bacterial growth rate decreased. WebThe starting point to test for IPTG induction should be a well-oxygenated fairly fresh culture. The desired OD600 is in the range of 0.5-1.0. Your starting culture should be split into two identical growth flasks. One will have IPTG added to induce T7 RNA polymerase, and hopefully our target protein. flair seats
