===2) Degradation Time of GFP=== | |||
Test the half life of GFP protein in an in vitro chassis. To test this a purified sample of known [GFP] are added to an in vitro chassis, then fluorescence will be measured at regular time intervals.

In addition, temperature may affect the half life of GFP and so the half life will be measured for an appropriate temperature range.<br> | |||

- To fine-tune the in vitro system
Conditions:
- 50μl in vitro chassis
- DNA concentration
Variables:
- Rate of GFP synthesis
- Life span of chassis
- Response time
- Temperature change 4oC, 25oC, 37oC
- Type of gradients: Pulse(5 min, 1 hour)
- Temperature change : from 4°C to 25oC, 37oC and vice versa
- Time period before increment: 30 min, 1h, 2h (subject to change)
- Temperature period maintained: 5 min, 15 min, 30 min, 1h, 2h
Sampling:
- Every 30 min interval.
- Every 15 minutes for 2 hours after change in temperature.
- Every 30 minutes thereafter.
Repetition:
- 3 repeats
Controls:
- Negative Control: In vitro system only
- Positive Control: In vitro system with purified GFP added
