Wet
GVP Cluster
- → DONE Isolate plasmids from E.coli Top10 BBa_J23101 cells
- → DONE Plate E.coli Top10 BBa_J23101 cells from o.n. culture
- → TODO
Pellet remaining cells for short storage in -20 box(not needed)
- → DONE Place the four test cultures with and without GVP on table at room temperature (make foto)
- → DONE Look at plates stored at 37C with BBa_J61002-pArsR+/pZntR+/pCueO+ and use colonies to grow o.n. cultures for plasmid isolation
Plates
Showed single colony growth on plates with J61002-pMEtal+RBS-RFP plasmids, and were stored in the fridge for future preculture growth.
- → The plates with high and low concentration of transformed cells showed colonies in the expected ratio.
- → On the plates for pZntR+ and pCueO+ no colonies were dark red, indication of ligation of the original high constitutive promoter back into the J61002 vector, or uncut plasmid which was transformed.
- → The plates with pArsR+ plasmid showed only a few non-coloured colonies, mostly medium red colour, andn a few dark red colonies. It was already thought that the pArsR is a bit leaky and causes expression of RFP.
Over Night Cultures
- → Both cultures of BBa_J61002-J23101 showed growth, and can be used for plasmid isolation.
Plasmid Purification
Plasmid isolation was performed on the cultures of E.coli TOP10 containing plasmids [http://partsregistry.org/wiki/index.php?title=Part:BBa_J61002 BBa_J61002] with [http://partsregistry.org/wiki/index.php?title=Part:BBa_J23101 BBa_J23101] constitutive promoter with the "Sygma-Aldrich™ [http://www.sigmaaldrich.com/life-science/molecular-biology/dna-and-rna-purification/plasmid-miniprep-kit.html GenElute™] Plasmid Miniprep Kit".
- From each tube 4mL of culture was collected in one 2.0mL cup, and the cells were pelleted by centrifugation for 1 min. at max. speed and the supernatant discarded.
- Plasmids were eluted with 40μL MQ and stored in the fridge
Transporters
Metal Accumulation
- Transform E. coli with pSB1AC3-fMT, MymT, SmtA ligations
- Use chemically competent cells and transform using heat shock (37°C)
- Transform ligation mixtures of
- pSB1AC3 + MymT
- pSB1AC3 + SmtA
- pSB1AC3 + fMT
- pSB1AC3 (self ligation control)
- pSB1AC3-H + RFP (31-07-09; positive control)
- MQ (negative control)
- Plate on LBAmp and put o/n in 37°C
