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.
