The LuxPR PCR products were purified and digested with EcoRI and PstI, then ligated with EcoRI-PstI cut pSB1C3, the iGEM 2010 standard backbone. We got the pSB1C3-LuxPR plasmid successfully.

Demonstration of Releasing System [contains the part BBa_k419003 (pLuxPR-Lysis device) in the iGEM 2010 standard backbone pSB1C3]

A single colony of releasing system E. coli was inoculated in the LB/chloramphenicol medium at 37℃. After 8 h of culture, we found that the LuxPR was auto-activated and lysis device was expressed causing the lysis of E. coli host. In our observation, we found that the autolysis of the host bacterial was almost completed after 8 hours. The result indicated that other factors may be involved in the activation of the luxR responsive promoter.
