We attempted to amplify Cro through PCR and cut it out of a gel. Cro will be used to induce the lytic cycle of lambda. We believe that when there is an abundance of Cro, there will be an increased lysis of lambda.

Moving right along, we cloned the CRO gene from bacteriophage lambda into pIG12, a vector with the arabinose-inducible pBAD promoter. We transformed the ligated plasmid into our target strains, TT9901, TT9907 (which have bacteriophage lambda integrated into their genomes as a prophage) and TT25281 (our control without the lysogen) by electroporation.

We did not see any plaques when we plated our transformed strains on arabinose! We wondered: is CRO not actually ligated into our vector? CRO, when overexpressed, downregulates itself; is there too high a concentration of CRO? Or is it possible that CRO alone isn't a sufficient factor to induce lysis? We learned by sequencing that CRO was not in our vector, and furthermore, that our primers to amplify CRO for another organism, not CRO from bacteriophage lambda! The correct primers we designed, and arrived.

| June 10 - June 23
With the correct primers, DMSO, and fresh template, we performed a successful PCR reaction of CRO. We continued the cloning process by digesting pIG12 and CRO, ligating them together, and transforming the ligated plasmid into DH5a E.Coli.
