Metal Sensing Team
Introduction and Outline
So far we have transformed DH5-alpha E. coli cells with two synthesized BioBricks, which are the cotC-GFP-smtA and the kinA BioBricks. The cotC-GFP-smtA BioBrick is involved within the metal sensing sub-project whereas the kinA BioBrick is involved with the Stochastic Switch sub-project. The Metal Sensing team have since taken these transformant colonies and used them to set up LB+kanamycin cultures for mini-preps and midi-preps; these were then left overnight in the orbital shaking incubator and are awaiting processing today. However there are a range of tasks which need to be accomplished today; these are listed below:
- Prepare Mini-preps of the kinA and cotC-GFP-smtA transformants
- Carry out the mini-prep processes
- Analyse the mini-prep DNA by treating with restriction enzymes.
- PCR the cotC-GFP-smtA BioBrick with pMK15 and pMK16
- Set up the PCR
- Run the PCR for the correct duration
- Analyse PCR products through DNA gel electrophoresis
- Clean up PCR products if PCR reaction proves to be successful
- Midi-prep cotC-GFP-smtA, kinA, pGFP-rrnB, pMUTIN4 and pSB1AT3
- Carry out the five midi-preps.
- Quantify the midi-prep samples
- Run the midi-prep samples on agarose gel through DNA gel electrophoresis
- Run products from a PCR reaction involving arsR and cadA DNA
- Run PCR products on gel
- If successful, clean up fragments, run on gel again, cut with restriction enzymes NheI and BamHI, clean and then ligate together fragments.
Procedure
The following procedures were carried out:
Freeze the kinA and cotC-GFP-smtA transformant cells
Instead of preparing mini-prep samples from the two groups of transformant E.coli cells (i.e. kinA transformed E.coli cells and cotC-GFP-smtA transformed cells), we instead took the decision to use the inoculated 5ml LB tubes in freezing the cells. Analysis of the midi-prep samples will be used to determine whether the BioBricks have been truly transformed - this decision will both save time and also provide a back-up stock of cells for future work. This procedure was carried out by James using the protocol
PCR the cotC-GFP-smtA BioBrick with pMK15 and pMK16
Midi-prep cotC-GFP-smtA, kinA, pGFP-rrnB, pMUTIN4 and pSB1AT3
Run products from a PCR reaction involving arsR and cadA DNA
Results
We took the decision to run 4 sets of DNA samples on 0.8% agarose gel - this includes the midi-prep samples (i.e. cotC, kinA, pGFP-rrnB, pMUTIN4 and pSB1AT3), products from a PCR reaction involving cotC, futher midi-preps of pMUTIN4 and digests from midi-prepped DNA the Stochastic Switch team have prepared (i.e. sac, ara and sleB) The resulting GelDoc photograph can be seen below:
