<font size="3" font face="Calibri"> This is the start of Spring Term at BYU! The weather is finally getting better: no more snowing. And we are ready to do some serious lab work! While we are waiting for our mutgen, 5-bromodeoxyuridine, to arrive, we decided to start this term with establishing the basic procedures for our direct evolution method. Specifically, this involves making sure that we can (1) grow and amplify T7 phage in liquid culture, (2) select for smaller phage using concentrated top agar, and (3) amplify phage from a single plaque. During these two weeks, we also designed primers for cloning and sequencing T7 capsid proteins as well as mapped out detailed procedures for both cloning T7 capsid proteins and applying mutagen. </font>

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.

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.
