iGEM Grenoble 2012

Project

July

week 27 week 28 week 29 week 30

Week 30: July 23rd to 29th

Goal of the week:

Test the Gibson Assembly and the transformation protocols, recover and amplify some biobricks involved in our genetic networks :
  • pAra/Bad_RBS_GFP (1300bp)
  • RBS_Cya (2600bp)
  • fha (80bp)
  • eCFP (800bp)
  • pSB4K5 (2400bp)

Monday, July 23rd:

We did PCRs with HF Phusion enzyme (protocol) on miniprep in order to amplify pAra/Bad_RBS_GFP, and on colony to amplify RBS_Cya. We did the PCR both with and without DMSO.

To separate the PCR products (12/07/23 and 12/07/20), we prepared a 1.8% TAE agarose gel.
Migration conditions = 100V during 30 min.
In order to reveal the DNA fragments, we used EtBr.

We saw primer dimer bands and the bands corresponding to the amplified fha1 sequence (lane 2 & 5). For the other, there was a PCR condition problem.

We realised a DNA extraction (protocol kit: Nucleospin extract II) from the two fha PCR products (PCR product code = 120723AM_PCR_020).

We did touchdown PCRs with HF Phusion enzyme (protocol) on digestion product (eCFP E0022 and E0422) (12/07/20) in order to amplify eCFP. We did the PCR both with and without DMSO.

Using iGEM 2012 biobricks we transformed (new protocol) BW25113 WT competent cells (protocol) with pSB4K5.

Tuesday, July 24th:

To separate the PCR products (12/07/23), we prepared a 1.3% TAE agarose gel.
Migration conditions = 100V during 30 min.
In order to reveal the DNA fragments, we used EtBr.
