Paola Gallardo. New parts fecA*, fecI, fecR*, PfecA, gltB and gltD*, their composite parts (fecI-fecR*, fecR*-PfecA y fecI-fecR*-PfecPG) and the vectors, that will be used in the ligation reactions later, were purified by GFX protocol. All of them were previously amplified. The first ones were obtained by PCR reaction from E. coli K12, and the others were extracted from the biobricks distribution 2010. After that, these parts were bound using restriction sites. Finally, they were transformed in E. coli and spread in LB+Cm plates.

David Caballero. Repetition of PCR reactions (in former experiments not completely satisfactory) to create biobricks: fecA*, fecR*, fecI*, PfecA, gltB, gltD**. PCR reactions were made in duplicate for each part. There were 19 PCR reactions in total: two for each simple part, one control without primers and two for the composite parts fecI-fecR*, fecR*-PfecA y fecI-fecR*-PfecA, taking advantage of the fact that these genes are consecutive in the E. coli genome.

PCR reactions were analyzed by 0.8% agarose gel electrophoresis. Results were not satisfactory: the gel overheated and ran for too long (1h and 30’), and fragments below 2 kbp ran off the gel. It was necessary to repeat the electrophoresis.

Assembly Team

First Fragments Assambly. We have named each part “UPO+(a number)” to identify the parts in a easier way.

• UPO 16 + UPO 3 (BBa_C0083 + BBa_B0015)
• UPO 1* + UPO 19 (BBa_J23100 + BBa_J45319)
• UPO 2* + UPO 13 (BBa_B0030 + BBa_E0040)
• UPO 1* + UPO 2 (BBa_J23100 + BBa_B0030)

1. Digestion of the fragments we required.
2. Purification of the DNA by using the kit GFX.
3. Enough time to ligate the DNA. They all use the lineal vector pSB1C3, except for UPO1+UPO2 (UPO2 is an ampiciline resistant vector)
4. Transformation in E. coli DH5α
5. Cultures are made on plates with Cm and Am
6. While waiting, we prepared LB medium and agar to make electrophoresis

We could not use the LacZ biobrick, maybe because this fragment is defective.
