Method: Have the following parts: dT [28 ng/(µL)]; lumazine [78 ng/(µL)]; psB1C3 [14 ng/(µL)].

Require 500 ng DNA each part in a 50(µL) rxn therefore 17.9(µL) dT and 6.4(µL) Lumazine. Need 250 ng pSB1C3 or 17.9(µL)

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

2 HB2 10 2

3 HB3 10 2

4 HB4 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.

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.

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).
