Method: Used Plasmid DNA Purification by Alkaline Lysis (Large Scale AKA Maxiprep protocol.
Results: Chloroform, DNA and isopropanol were mixed and therefore no products could be recovered.

September 20, 2010

ADS

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

8 RFP2 10 2

9 RFP3 10 2

Results:

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.

Transform 1µL into DH5α subcloning efficiency cells
Obtained TNTC colonies
Started overnight 5mL cultures for miniprep and insertion into pSB1C3 vector.

Objective: PCR the N-term fusion tag onto RFP (E1010) using sloppy annealing of the YFP/CFP fusion primers.

Composition of each PCR tube:

Component Volume(µL)

10x Pfu Buffer w/ MgSO₄ 2

dNTP (10mM) 1

N-term Fus Prefix 1

Biobrick Suffix 1

MilliQ H₂O 12.8

Template DNA (J04450) 2

Pfu DNA Polymerase 0.2

PCR conditions:

Step Temperature (^oC) Time (mins) Number of cycles

Initial Denaturation 95 2 1

Denaturation 95 0.5 25

Annealing 47.6, 50.5, 53.8 (gradient) 0.5 25

Extension 72 2 25

Final Extension 72 10 1

Results: Gel has not been run. Have decided to order RFP specific primers for next year.
