Also we should grow samples on the same marker, as we've done this experiment on both T and K resistance. Since both vectors also contain an ampicillin resistance, we should grow on ampicillin. Finally we still need to measure total protein content, as this is a better reference for protein content as OD, which we've used now for correction.</ins></div></td></tr>

==Luciferase Assay==<br />
Today we've done our first luciferase assay. The samples we had in the end were either K115034 (34) or K115012 (12, control).<br />
===Samples===<br />
A: 12, Growing overnight with induction at room temperature, lysed by sonification<br />
B: 34, Growing overnight with induction at room temperature, lysed by sonification<br />
C: 12, Growing overnight with induction at 37oC, lysed by sonification<br />
D: 34, Growing overnight with induction at 37oC, lysed by sonification<br />
E: 12, Growing overnight without induction at 37oC, induce next day for 5 hours at room temperature, lysed by sonification<br />
F: 34, Growing overnight without induction at 37oC, induce next day for 5 hours at room temperature, lysed by sonification<br />
G: 12, Growing 2 times overnight with induction at room temperature, lysed by sonification<br />
H: 34, Growing 2 times overnight with induction at room temperature, lysed by sonification<br />
I: 12, Growing 2 times overnight with induction at room temperature, lysed by kit buffer<br />
J: 34, Growing 2 times overnight with induction at room temperature, lysed by kit buffer<br />
K: 12, Growing o/n at 37oC without induction, to test R0080 for leakiness..<br />
<br />
===Protocol===<br />
The protocol used in the case of most samples, when lysed by sonification was:<br />
1. Grow as indicated above and induce immediately, unless stated otherwise <br />
2. Pellet 3 ml of cells <br />
3. Resuspend in 100 ul 15 mM Tris HCl <br />
4. Destroy by sonification (3 * 15 s) <br />
5. Freeze at -20 <br />
6. Add 20 ul of lysed cell sample to a well <br />
7. Measure by automatic dispension of 100 ul of Luciferase Assay buffer (Promega) <br />
<br />
If lysis by kit buffer (Promega) was used, the protocol became:<br />
1. Grow as indicated above and induce immediately, unless stated otherwise <br />
2. Pellet 3 ml of cells <br />
3. Resuspend in 100 ul 1X lysis buffer <br />
4. Leave at room temperature for 15-30 minutes <br />
5. Freeze at -20 <br />
6. Add 20 ul of lysed cell sample to a well <br />
7. Measure by automatic dispension of 100 ul of Luciferase Assay buffer (Promega) <br />
<br />
===Results===<br />
After a lot of fine tuning of the luminometer, the luminescence values were obtained as shown in graph 1. <br />
