Digestion was incomplete and need to repeat experiment
Experiment was repeated on 8/9/14 and digestion was successful. The desire bands were excised and purified. Unfortunately the image file was lost due to a technical problem prior to routine file backup. However, further experiments continued to use parts isolated on this date and bands of correct size were present through all of these steps.

*Did not complete Gel Purification
Plan for Tomorrow:
1) Finish Gel Purification (Possibly Re-Run. I believe I cut wrong fragment)
2) Make chloramphenicol plates
3) Resuspend YF1 & FixJ, Blue Light Sensor (Plate 1, Well 10N; 1:10N)
4) Resuspend FixK2 Promoter (Plate 1, Well 19G; 1:19G)
5) Transform and Plate (YF1 & FixJ) and FixK2 Promoter
If able to obtain Kanamycin:
1) Make Kanamycin plates (2-3)
2) Transform and Plate mCherry Bomb (3.4 uL of plasmid left)
Lab Work 8/14/14:
Plan:
1) Re-Run mRFP1 on Gel and then Gel Purify
2) Make Chloramphenicol Plates
3) Dilute mCherry Bomb and nanodrop
3a) If enough DNA is present, run PCR (1.4 ng/uL only)
3b) If not enough DNA is present, make Kanamycin plates
4) Resuspend YF1 & FixJ, Blue Light Sensor (Plate 1, Well 10N; 1:10N)
5) Resuspend FixK2 Promoter (Plate 1, Well 19G; 1:19G)
6) Transform and Plate (YF1 & FixJ) and FixK2 Promoter (Chloramphenicol)
7) Transform and Plate mCherry Bomb plasmid (Kanamycin)
