Did some minipreps today. Then nanodropped them:

I planned to test the competent cells today. For that I chose a three DNA samples. One is a diluted biobrick λp-rep for testing electro-competent cells, λp-GFP which had very high DNA concentration and biobrick pSB1K3 which had a normal DNA concentration.

Cultures in all pSB4C5 tubes. Did miniprep on all tubes and also made a plate.
| Part | Concentration ng/µl | 260/280 | 260/230 |
| pSB4C5 I | 123.0 | 1.91 | 2.06 |
| pSB4C5 II | 125.8 | 1.92 | 2.29 |
| pSB4C5 III | 130.7 | 1.95 | 2.07 |
Todays gel confirmed that oriT-R digestion failed and pSB4C5 is way too large.

R751 cells arrived. Made two plates without antibiotics.
Digestions were started:
| position | parts | volume in µl |
