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

IngredientVolume(µL)
MilliQ H20 Water15.75
Orange Buffer (10x)2
pDNA (rbs-xylE)2
EcoRI0.25

Unrestricted Control

IngredientVolume(µL)
MilliQ H20 Water16
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:

<tr><td>1</td><td>Restricted RBS-xylE</td><td>10</td><td>2</td></tr> <tr><td>1</td><td>Unestricted RBS-xylE†</td><td>1</td><td>2</td></tr> <tr><td>1</td><td>1kb Ladder††</td><td>2</td><td>2</td></tr></table> † Added 9µL MilliQ H2O
†† Added 8µL MilliQ H2O

Objective: Ligate pLacI to sRBS-Lum-dT using the three antibiotic assembly method (according to Tom Knight's protocol). Previous ligation had miniscule quantities of DNA in ligation, not surprising it didn't work.
