Parameter Value and Description
Optimum temperature The T7 promoter has a highest output at 25°C, with a one-fold increase in GFP molecules synthesized compared to 37°C. The T7 promoter also has a minimal amount of output at 4°C.
Expression Life-span The rate of GFP synthesis by the T7 promoter reaches a peak at around 30-60 minutes.
Peak Expression The production of GFP decreases to minimal levels after 2 hours and tends towards nil after 4 hours.

Team Warsaw 2010's measurement

Absolute promoter strength: 41,8pg RNA/minute/ug substrate DNA. It equals 8,92 microPoPS
