PCR of pCola plasmid (Geranyl Synthase)
by Melanie
we use the same protocol as yesterday but we have done 8 tubes to apply a gradient in the thermocycleur during the third step:
- 57°
- 56.3°
- 55.1°
- 53.3°
- 51°
- 49.3°
- 47.9°
- 47°
PCR protocol: 98° --> 2min
5 PCR cycle:
| time | 10sec | 20sec | 45sec |
|---|---|---|---|
| temperature | 98° | (depending on the tube - see the gradient) | 72° |
25 PCR cycle
| time | 10sec | 20sec | 45sec |
|---|---|---|---|
| temperature | 98° | 72° | 72° |
and last step: 72° during 10min
but we don't have any results

Our lemon will be made of agar gel. We first thought of buying silicone mold. But I'll try to make the mold only with agar, cheaper than silicone.
First attempt :
I put about 100ml of hot liquid high density agar ( 35mg/ml ) in a becher and then immerged a test piece to mold.
I let the whole thing cool down in a refrigerator for 2 hours.
Then, I unmold the test piece by cutting accurately around the mold. The mold is placed back in the becher ( without the test piece ), pierced delicately to the cavity and filled up with regular liquid agar ( 20mg/ml ).
Cooled down again in a refrigerator for 2 hours.
BEWARE : The regular agar ( 20mg/ml )is heated to make it liquid but you want to put it in the mold. Too hot, and you will melt the mold. Too cold, and your agar will turn back solid.
Second attempt : Same protocol than the first attempt, but with higher density agar ( 50mg/ml ).
Result : Opening of the first mold, the second one is kept in the refrigerator for tomorow.
From the left to the right :
- agar mold (35mg/ml) cut in two parts
- agar test piece extracted
- original test piece.
- agar mold (50mg/ml) still intact.
