Digestion Experiment
| Sample | Condition |
| 5+ | 5 sec. in microwave |
| 5- | 5 sec. room temperature |
| 10+ | 10 sec. in microwave |
| 10- | 10 sec. room temperature |
| 15+ | 15 sec. in microwave |
| 15- | 15 sec. room temperature |
| 1 hr | 1 hour at 37 C |
| W+ | Water control microwaved for 10 sec. |
| W- | Water control at room temperature |
| Component | 1xvol.(μL) | 9xvol.(μL) |
| Buffer 3 | 1 | 9 |
| BglI | 1 | 9 |
| Water | 7 | 63 |
| DNA | 1 | 9 |
- All samples inactivated at 65°C for 20 minutes.
- Ran the products on a 1% gel at 80V for 40 minutes.
- No visible difference between: 5+ and 5-; and 15+ and 15-. 10- matches 1 hr better than 10+, which showed incomplete digestion. All samples other than 1 hr showed varying degrees of incomplete digestion.
- Microwave protocol is therefore not useful for time frames tested. However, current digestion processes can be shortened from 1 hour to 15 minutes.
Digestion of Constructs OA, OB and T Amp Product
| Component | Volume(μL) |
| Buffer3 | 1 |
| BSA | 1 |
| Water | 5 |
| SphI | 1 |
| PstI | 1 |
| DNA | 3(1 μL each) |
- Deactivated at 80°C for 20 minutes
- Added 1μL ligase and 1μL ATP to tubes.
- Left one sample over the weekend to ligate, another for 5 seconds in the microwave, then to the 4°C fridge, and one for 10 seconds in the microwave then to the 4°C fridge.
- Inoculated 5 samples each of Matt's 3:1 and 6:1 PTP2/PSSA42 construct for removal tomorrow by Corie.

Transformation
- p1T(0A0B) and pSSA14 + 0B were transformed
Gel
- Gel was run of p1T right after the first gel extraction and after digestion with ClaI and ligation
