Part:BBa_K4156119

XOR gate-HlyE

XOR gate-HlyE consists of an XOR logic gate ( BBa_K4156117 ) and a downstream HlyE ( BBa_K4156084 ) sequence, and tests the performance of the XOR gate by detecting the red fluorescent signal.

Usage and Biology

The construction of this part is similar to XOR gate-mRFP ( BBa_K4156124 ). The difference is that we replaced the mRFP protein with the HlyE therapeutic protein. This is to verify the therapeutic power of the recombinant strain under XOR gate control. After co-incubation of the recombinant strain with cancer cells, cell viability was monitored using the CCK8 assay to assess the therapeutic power of the recombinant strain and the reinforcing effect of the XOR gate.

Characterization

We used three different promoters in combination with XOR gate-HlyE to characterize the therapeutic efficacy of bacteria under the control of different promoters and TP901 coupled logic gates, and with the addition of lysis genes.
