ADS

Objective: Analyze PCR of mms6 (HB) and fluorescent proteins (AV).
Method: Analyzed on 2% TAE agarose gel.
Load order:

<td>0.5</td><td>2(+10 H₂0)</td>

<tr><td>7</td><td>RFP1</td><td>2</td><td>10</td></tr> <tr><td>8</td><td>RFP2</td><td>2</td><td>10</td></tr> <tr><td>9</td><td>RFP3</td><td>2</td><td>10</td></tr></table> Results: ADD IMAGE

• mms6 was not amplified
• RFP was amplified
  • Expected size is ~800bp
  • Actual size is >1000bp
    • We believe that the suffix segment of the fusion primer annealed rather than the FP segment. This would cause the promoter (R0040) of J04450 to be amplified, adding ~200bp, giving a final size of >1000bp.

Objective: Confirm assembly (3 antibiotic) of K118021 and B0015 from Sept. XX, 2010 via PCR.
Method: Set up 50uL reaction mixture with 2uL of ligated DNA. Used VF2 and VR primers.
Results: See gel.
Conclusion: Assembly did not work as intended. Used PFU setting on Thermocycler

Objective: Insert xylE (with N and C terminal fusion standards, obtained by PCR of K118021 by KG) into pSB1C3 plasmid for submission to registry.

Method:

• Restriction of xylE PCR product and pSB1C3 (containing J04450 biobrick) via BioBrick Method using EcoRI-HF and PstI (Enzymes from NEB)
• Ligation of xylE PCR product and pSB1C3 via BioBrick Method using T4 DNA ligase (Enzyme from NEB)
• Transform into Library Efficiency Compentent DH5α Cells (Invitrogen)

Results:

• Obtained too numerous to count (TNTC) colonies.
  • Obtained ~100 white colonies (indicating removal of RFP and insertion of new BioBrick)

Note:
Parent plasmid (from PCR) not digested, possibly K118021 moved into pSB1C3 backbone.

Follow-up:
Screen white colonies by addition of catechol to solution containing white cells.

JV

Objective: Characterized catechol degradation by xylE enzyme

Method: Measured absorbance of catechol (275nm) and 2-hydroxymuconate semialdehyde (380nm).

• Protocol:
• 1) Grow cells in M9 minimal medium
• 2) Take 1/10 dilution of cells
• 3) Introduce 1µL of 0.05M catechol solution into the cell dilution. (Final concentration of 50&microM;).
• 4) Quench the reaction with 5A% w/v trichloroacetate at certain time points. (0,15sec, 30sec, 45sec, 60sec, 2min, 3min, 4min, 5min, 10min).
• 5) Spin down cells.
• 6) Measure absorbance of supernatant.

NOTE: In all transformations, heat shock step was missed. HOWEVER, all transformations showed significant number of colony forming units.
Objective: Move xylE (two biobrick; one with Fusion prefix, one with fusion suffix) into pSB1C3.
Method:

  • Incubated 30 min at RT
• Transform into Subcloning Efficiency Compentent DH5α Cells (Invitrogen)

Results: TBD
Follow-up: TBD
