26 kDa, Figure 3, samples 7, 8 and 9. We attribute lack of cI bands in our T7 Express cell lysate due to T7 RNAP leakage, which would silence the cI expression. This hypothesis requires further investigation, however our preliminary results suggest the circuit could be functional. | 26 kDa, Figure 3, samples 7, 8 and 9.

cI-Cro bacteriophage lambda lytic cycle regulatory circuit
The cI-Cro construct contains a circuit for the production - via a constitutive promoter - of the cI repressor protein (also known as the Lambda Repressor), which is responsible for keeping bacteriophage lambda in the lysogenic cycle through the cooperative binding of two repressor dimers to the DNA, repressing the Cro gene. The circuit uses a T7 promoter to drive the expression of the Cro gene in the opposite direction to the cI gene, essentially silensing the expression of the cI gene. Thus, the presence of the T7 RNA polymerase in the system enables the switch from the lysogenic cycle to the lytic cycle.
