July 1st, Sunday

Dylan and Caleb set up two gels for electrophoresis. Caleb's was 1% agarose in BIO-RAD Mini-Sub Cell system for continuation of ladder test using SYBR Green, containing NEB 100 bp ladder, NEB 2-log ladder, Promega 1 kb ladder and run at 100V. Dylan's was 1% agarose in Owl box using ethidium bromide, containing the nah operon PCR product from previous night, and run at 55 V. Our plates of DH5a transformed with p21 ligated into pBBRBB with mtrB grew only one colony, possibly contamination. Dylan ran a colony PCR and got a smear, suggesting that the PCR of p21 or the ligation did not work. Because we learned that our SYBR Green was causing ladder to run strangely, Dylan decided to redo a Vent PCRto amplify the salicylate reporter region out of p21. Also, a liquid culture of JG700 was prepared, as well as replating of p21, p22, JG700, JG1220, JG1537, JG1219. (See: Strain List)

June 28th, Thursday

This morning, Dylan and Caleb did minipreps of all the cultures from the day before. They then set up a gel of Phusion PCR of nahR from Wednesday. That afternoon, Swati set up a transformation of p14k into DH5a cells. The cells were recovered for 1 hour at 37C in LB before plating. Dylan set up sequencing of the Gibson products with our newly designed primers while Shweta gel extracted the nahR from the gel set up by Dylan and Caleb. After Shweta’s gel extraction, Swati set up a double digestion of the product with EcoRI and AscI. That night, Steven ran a gel of the nahR digest while Spencer set up overnight cultures of p14k, p16k, pSB3C5, and pBBRBB.

June 29th, Friday

In the morning, Dylan set up a Vent PCR to amplify p21a (salicylate sensing region) and his previous Phusion PCR band. That afternoon, he gel purified the PCR products and set up a double digestion with EcoRI-HF and AscI. Spencer miniprepped the overnight cultures from Thursday. Later that night, Dylan set up another Phusion PCR to amplify the nah operon from Gibson colony 1 and to append Biobrick cutsites into the product for future ligation into pSB3C5. Swati started the gel extraction of p21a.

June 30th, Saturday

Today, Dylan started out the day by running the PCR of the Gibson colony 1 on a gel, gel extracted the band, and set up another Phusion PCR with an extension time of 3 minutes to get more of the construct. That afternoon, Swati finished her p21a gel extraction and dephosphorylated pBBRBB+mtrB for ligation with p21a. Swati desalted the ligation on Millipore membrane paper and electroporated her ligation into DH5a. After letting the cells recover in LB for 1 hour, Swati plated her ligations. Later that night, Steven and Spencer set up two transformations into PNNL electrocompetent Shewanella one at a voltage of 0.75 kV, and the other at 0.55 kV prescribed by Myers and Myers.
