Salicylate Inducible Suppressing System

DNA purification gel agarose

by Fabio

Once the segregate process made yesterday by electrophoresis, the DNA correspondent to the core of BBa_K1372000 was purified from the gel agarose.

Segregate Process Protocol

Ligation

by Fabio

The final step to have a BioBrick Assembly is the Ligation reaction.

TODO: illustration of the process

• BioBrick BBa_K1372000 (Salicylate promoter + NahR + RNA suppressor) as Part A
• BioBrick BBa_B0015 (Terminator) as Part B

BioBrick Assembly - Ligation Protocol

Lemon Sent

PCR of pCola plasmid (Geranyol 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:

25 PCR cycle

and last step: 72° during 10min

but we don't have any results

Protocol

Polymerase chain reaction

by Sean & Pierre

for this PCR, five tubes of each of the following Bio-bricks were prepared.

BBa_K517003

BBa_K762100

Tubes were placed in PCR machine with the following parameters.

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 ). I let the mold with the test piece in it at refrigerator for the night.

Result : Opening of the first mold, the second one is not cut yet.

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.
