WebThe optimal OD 600 for induction is 0.4 to 0.6. At what temperature should I perform my induction? Induction can be performed at a variety of temperatures, ranging from 37°C to 30°C to room temperature. A lower temperature typically requires a longer growth time.

Bars and error bars represent the mean OD 600 and standard error of four biological replicates after 12 h induction, respectively. Samples not connected by the same letters are significantly different (Tukey HSD, α = 0.05).
