LOVTAP plasmid AND TrpR plasmid were transformed in competent E. Coli following received protocol, and grown overnight (see Lab book for more details).
One problem: we actually don't know TrpR plasmid resistance, so we tried with three resistances available in the lab: Amp., Kana. and Chl. LOVTAP is in a plasmid called pCal-n (see picture below):

pCal-n plasmid

Some comments on the plasmid:
-CBP is a small peptide with which we could purify LOVTAP protein
-Thrombin target is a nucleotidic sequence that can be recognized by thrombin a peptidase. This peptidase will cut CBP once LOVTAP is purified

We have to grow the 3 strains generously sent by Tom Beatty

The three strains are :

• R.Palustris CEA001 (wild type) ; should be grown on LB medium only
• R.Palustris BPHP1+ ; should be grown on LB with gentamycin (100 micrograms/ml)
• E.Coli DH10B (pBPH/hmu0) ; should be grown on LB with gentamycin (20 micorgrams/ml)

The transformed LOVTAP and TrpR worked well (N.B. the plasmid of TrpR is pUC19 so the antibiotic resistance is Amp -> see below)

pUC19 plasmid

We did the glycerol stock, located in the -80 fridge, first floor of the iGEM compartement.

Then, a miniprep was done with both cultures. A LOVTAP plasmid aliquot was done, a TrpR plasmid aliquot was done, located in the -20 fridge, 2nd floor.

1. R. Palustris culture grew. A glycerol stock has been done. A pellet is on the fridge level 2, waiting for a miniprep.

2. iGEM parts have been transformed: A, well kit plate 1: 1C
- BBa_B0010 (terminator), resistance: A, well kit plate 1: 1C
- BBa_R0010 (promoter LacI), resistance: A, well kit plate 1: 1C
- BBa_B0030 (RBS), resistance: A, well kit plate 1: 1C
- BBa_E0240 (RBS-GFP-TER), resistance: A, well kit plate 1: 1C
- BBa_I13507(RBS-mRFP-TER), resistance: A, well kit plate 1: 1C
- BBa_I13002(pTetR-RBS), resistance: A, well kit plate 1: 1C
- BBa_I6007 (inverter TetR), resistance: A, well kit plate 2: 1C
