JV quantified the amount of DNA in gels run to date using ImageJ software. Results to be posted in working plasmids box.
Objective: Transform plasmids into DH5α
Method: Follow competent cell transformation protocol to transform the following:
From our ligations:
- pLacI-sRBS-Lumazine-dT
- pLacI-sRBS-Lumazine-dT
- mms6 (A6)
- mms6 (B6)
- xylE (C4)
- xylE (B4)
From the 2010 Parts Distribution:
- ECFP (Bba_E0020)
- EYFP (Bba_E0030)
- BglII Endonuclease (Bba_K112106)

(In Lab: JV)
Objective: Isolate plasmid DNA of RBS-xylE (BBa_J33204) from DH5α cells and confirm results.
Method: "Mini-prep" the plasmid DNA using boiling lysis miniprep. Then restrict the DNA once and run on a 1% agarose gel (TAE).
Restriction Reaction
| Ingredient | Volume(µL) |
| MilliQ H20 Water | 15.75 |
| Orange Buffer (10x) | 2 |
| pDNA (rbs-xylE) | 2 |
| EcoRI | 0.25 |
Unrestricted Control
| Ingredient | Volume(µL) |
| MilliQ H20 Water | 16 |
| Orange Buffer (10x) | 2 |
| pDNA (rbs-xylE) | 2 |
DNA was restricted for 80 minutes at 37oC.
Analyzed results on a 1% agarose gel. Load order as follows:
| Lane | Sample | Volume Sample (µL) | Volume Loading Dye (µL) |
| 1 | Restricted RBS-xylE | 10 | 2 |
| 1 | Unestricted RBS-xylE† | 1 | 2 |
| 1 | 1kb Ladder†† | 2 | 2 |
† Added 9µL MilliQ H2O
†† Added 8µL MilliQ H2O
Ran gel at 100V from 2 hours.
Results:
Conclusions: Plasmid DNA prep and restriction was successful.
Objective: Ligate rbs-xylE (Bba_J33204) to our double terminator, and insert it into the pSB1T3 plasmid backbone.
Method:
- Restrictions
- Restrict rbs-xylE wit EcoRI and SpeI (Red Buffer)
- Restrict the double terminator with XbaI and PstI (Tango Buffer)
- Restrict pSB1T3 with EcoRI and PstI (Red Buffer)
