ADS
Objective: Analyze PCR of mms6 (HB) and fluorescent proteins (AV).
Method: Analyzed on 2% TAE agarose gel.
Load order:
Lane Sample Volume
Sample (µL)Volume Loading
Dye (µL)1 HB1 10 2 2 HB2 10 2 3 HB3 10 2 4 HB4 10 2 5 HB5 10 2 6 100bp Ladder (Fermentas) 0.5 2(+10 H20) 7 RFP1 10 2 8 RFP2 10 2 9 RFP3 10 2
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.
Used PFU setting on Thermocycler
Results: ADD IMAGE
Conclusion: Assembly did not work as intended.September 21, 2010
ADS
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.September 21, 2010

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 50µM;).
- 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.
Results: Cuvette used interfered with Spectra.
