TRZ1 receptor under the control of the pOmpC promoter with iLov fluoresent reporter

We designed a new part (pompC+Trz1) to evaluate the impact in cell viability of the overstimulation of the endogenous EnvZ/OmpR system, through the establishment of a positive feedback loop between the Trz1 receptor and the ompC promoter. This construct was designed as an improvement of the existing TRZ1 receptor, which is already submitted to the iGEM registry. The co-expression of TRZ1 with the fluorescent reporter iLov allows rapid screening of transformants directly on the plate as shown in the image below.

In this SDS-PAGE a total protein extraction run is shown to assess the expression of TRZ1 in normal (5g/L NaCl) and high osmolarity (10g/L NaCl) at different dilutions.
