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.

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)
