'''May 17''': The control of the miniprep of luciferase was murky. This could have been due to contaminants in the LB, water, ampicillin, or pipet tips. A miniprep of both luciferase and EcoMscL was conducted. A new seed of luciferase was prepared. The miniprep of luciferase was digested with EcoRI and HindIII. The miniprep of EcoMscL was digested with XmnI. A gel with the digests was run but the EcoMscL showed no bands and the luciferase only had faint bands. | '''May 17''': The control of the miniprep of luciferase was murky.

There were two faint bands on the gel with the EcoMscL when there should have been three. Thus a new batch of Stable 3 bacteria were transformed with EcoMscL through heat shock. The gel with the psp-Luciferase turned out well and the gene was extracted from the gel. Ligation was not completed since the microcentrifuge tube with the pGFP cut vector could not be found due to labelling issues. |

May 15: Transformed Top10F' bacteria with the pGFP vector containing the Luciferase gene (hopefully the ligation worked this time).17:22, 15 May 2006 (EDT)
May 16: Transformation of Top10F did not work. The cause was an error in the extraction of the DNA from the the agarose gel. Completed a new agarose gel extraction of pGFP plasmid DNA, as cut by EcoRI and HindIII. Prepared a new seed of Top10F bacteria transformed with luciferase. Prepared a midiprep seed of EcoMscL.
May 17: The control of the miniprep of luciferase was murky. This could have been due to contaminants in the LB, water, ampicillin, or pipet tips. A miniprep of both luciferase and EcoMscL was conducted. A new seed of luciferase was prepared. The miniprep of luciferase was digested with EcoRI and HindIII. The miniprep of EcoMscL was digested with XmnI. A gel with the digests was run but the EcoMscL showed no bands and the luciferase only had faint bands.

A gel was run with the digests. There were two faint bands on the gel with the EcoMscL when there should have been three. Thus a new batch of Stable 3 bacteria were transformed with EcoMscL through heat shock. The gel with the psp-Luciferase turned out well and the gene was extracted from the gel.
