Commercial E. coli T7 S30

Cell-Free Systems (back to Intro) Introduction
Chassis description
 The Commercial E. coli T7 S30 extract was purchased from Promega. It was prepared by modifications of the method described by Zubay et al (1980). E. coli strain B deficient in OmpT endoproteinase and lon protease activity was used.

The simple constitutive gene expression device BBa_E7104 has been used to characterize this cell-free chassis

Temperature dependence

Graph 1. Graph of GFPmut3b synthesized (pmol) against time (minutes) at 4oC (dark blue), 25oC (pink) and 37oC. The simple constitutive gene expression device BBa_E7104 has been used. Each of the three coloured lines show average measurements based on three replicates of the experiment. The error bars represent the standard deviation of the measurements.
Peak time

Graph 2. Graph of rate of GFPmut3b synthesis (pmol per min) against time (minutes) at 4oC (dark blue), 25oC (pink) and 37oC (yellow). The simple constitutive gene expression device BBa_E7104 has been used. Each of the three coloured lines show average measurements based on three replicates of the experiment. The error bars represent the standard deviation of the measurements.
Expression lifespan

Graph 3. Graph of rate of GFP synthesis (mol per min) against time (minutes) at 4oC (blue), 25oC (red) and 37oC (green). The simple constitutive gene expression device BBa_E7104 has been used. Each of the three coloured lines show average measurements based on three replicates of the experiment. The error bars represent the standard deviation of the measurements.

Graph 4. Bar chart showing total GFPmut3b synthesized in 6 hours (pmol) at 4oC (dark blue), 25oC (pink) and 37oC (yellow). The simple constitutive gene expression device BBa_E7104 has been used. Each of the three coloured bars show average measurements based on three replicates of the experiment. The error bars represent the standard deviation of the measurements.
