- Digestions were left for 1:30 at 37°C
- 2.2 μL of DNA Loading Buffer were added to each reaction and loaded onto a 1% Agarose gel (TAE buffer). Gel was ran at 125 V for 30 min.

B15 undigested
|
- The undigested B15 in lane 6 appears as two bands on account of supercoiling of the B15 plasmid.
- Bands in lanes 2 - 5 were cut out and purified using a Qiagen Gel Purification kit
- The gel purification was done with 300 μL Buffer PB and 400 μL Buffer QG

- Note the very low concentration of NOSt+STOP. It is uncertain as to what caused such a concentration, but transformation proceeded anyways with max volume
- The ligation reactions were preformed at at 2:1 (insert to backbone) Molar Ratio

B21 Innoculation
Inoculated 3 colonies of B21 transformed E.Coli and set them to shake for 8 hours. We will maxiprep the B21 plasmid for use as a vector backbone.
PCR of Gal4DBD and Barnase, attempt 2
Ran 3 tubes of each for a total of 6.
7x Mastermix:
- 14μL DNTP
- 3.5μL Polymerase
- 28μL 5x Buffer
- 73.5μL DH2O
Each tube contained:
- 1μL Fwd primer
- 1μL Rev Primer
- 1μL Minipreped sample
- 17μL Mastermix
Reduced annealing temp to 50°C from 56°C which was the last attempt, ran otherwise identical LACIN program
Gel of Gal4 DBD and Barnase from second PCR attempt
Ran 1.2% E-gel of the 6 PCR product tubes.

QIAQuick Purification of PCR Product
Because colonies 1 and 2 of Barstar worked properly on last week's gel, the PCR products in those two tubes were combined and purified using the Qiagen PCR purification protocol.
- as there was about 25μL of PCR product in the two together, 125μL of PB buffer was added (5x the concentration of the PCR product)
- pipetted the mix into a QIAquick spin column, spun for 30 seconds at 13,000 rpm
- discarded flow-through
- added .75mL PE buffer to the column, spun for 30 seconds
- discarded flow-through, and spun again for 1 minute
- moved the column to a fresh eppendorf tube
- added 50 μL EB buffer to the column, spun for 1 minute
- labeled the eppendorf tube 'Barstar PCR purified'
