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

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

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:
