Nathan Puhl et al

Gel extracted two bands really closer to each other from PCR (August 1) at ~76 bp. Used Qiagen MiniElute kit. Results are in the hard copy lab notebook. Seems as if gel extraction was successful. ____ 2 color reporter system:

Set up digest of LacI and DT.

LacI - EcoRI and SpeI

DT - EcoRI and XbaI

Reaction mixture: 

-5 uL template
-5 uL NEB 2 Buffer
-0.5 uL BSA?
-1 uL RE #1
-1 uL RE #2
- 37.5 uL ddH20

Left at 37 C overnight. Heat deactivation (65 C) for 15 minutes.

Nathan Puhl, Roxanne

2 color reporter system:

Gel extracted LacI insert and DT vector. Didn't run gel yet.


August 13, 2008

Nathan Puhl and Sebastian

Verified and quantified the LacI and DT restriction digest products.

Set up a Ligase experiment for LacI and DT 

- 1.3 uL vector(DT)
- 8 uL insert(LacI)
- 2 uL 10x Ligase buffer
- 1.5 uL Ligase
- 7.2 uL ddH2O
- 20 uL total volume

Nathan Puhl, Munima, Selina

Poured 61 LB + Amp plates. Stored in iGEM 4 C fridge.

Roxanne

Used Qiagen Plasmid MiniPrep Kit to Plasmid Prep Last Year's Biobrick Parts that were Incubated overnight.

Ran Plasmids in a 1% Agarose Gel at 100 V for 30 minutes.

Christa, Munima, Sebastian

Did a plasmid prep on pSB1A7 using QIAprep Spin Miniprep Kit. Stocked 4- 50uL of pSB1A7 and stored in iGEM -20 C.

Sebastian, Nathan Puhl

Ran products from plasmid prep (pSB1A7 x 4 samples) on 1% agarose gel for 27 minutes. 

-Lane 1 - 1 kb GeneRuler ladder (2 uL)
-Lane 2 -6 pSB1A7 (3 uL) + 6x loading dye (2 uL); Mixed up what sample was in Lane 4, so Lanes 5 and 6 were run.

Conclusion: The bands appeared to be at the correct size for pSB1A7.

Christa, Munima, Nathan Puhl, Roxanne

Objective: Run a gel to confirm that appropriate inserts were amplified from the PCRs and do a gel extraction of the inserts to prepare them for the biobrick format. 

-Could not obtain a picture of the gel (1% agarose) of the half of the digested pSB1A7 (15 uL x 3 wells) and 
the recently amplified 
CheZ gene (15 uL x 3 wells) because the camera would not turn on. 
  The CheZ gene appeared at the correct size (~700 bp).
-Did a gel extraction of pSB1A7 and CheZ from that gel with the Qiagen MiniElute Gel Extraction kit. 
Final volume of each was 10 uL.
-Ran another 1% agarose gel to confirm that the gel extraction was successful. Ran 1 uL of each sample. 
Bands appeared at appropriate sizes. The concentrations of pSB1A7 
  and CheZ were estimated to be 25 ng/uL and 80 ng/uL, respectively.

Next step: Digest pSB1A7 with antarctic phosphatase. A restriction digest will be performed at a later date on CheZ to prepare it for insertion.
