Today we carried out the following procedures (in rough chronological order):

1. Checked the cell cultures transformed and plated out yesterday (8/6) for colony formation and made an approximate count of the number of colonies.

(plate number)-(location on plate) (no. of colonies)

2. Conducted a 'miniprep' to harvest and check concentration of the EpsE (molecular clutch) plasmids from 3 test tube cultures incubated since yesterday (8/6). Result of Nanodrop concentration check:

(test tube no.) [260/280] [260/230] (concentration)


      1           2.14      1.65     37.6 ng/ul
      2           2.07      1.95     62.9 ng/ul
      3           1.95      1.33     60.6 ng/ul

3. Prepared kanamycin antibiotic solution from kanamycin sulfate and MilliQ water. 100 mg kanamycin sulfate + 10 ml MilliQ water -> 10 ml of 10 mg/ml kanamycin solution.

4. Transformed compe[tent cells with the following parts to amplify them:

(plate number)-(location on plate) (antibiotic resistance)

Note: 2-24G and 2-12H were transformed yesterday but produced no colonies. 2-18F was marked for transformation yesterday but 2-15F was mistakenly transformed instead.

5. Treated a sample of EpsE-containing plasmids with EcoRI and SpeI restriction endonucleases to isolate and check length of amplified EpsE part. The plasmid-buffer-endonuclease mixture was incubated and left to react overnight (Incubation at 37 degrees Celsius began at 16:00).
