Nathan Puhl, Roxanne
-Ran all of the restricted pSB1A7 plasmid through a 1% agarose gel at 100V for 25 minutes. -Ran a gel extraction on the pSB1A7 cut plasmid, and ran a PCR clean-up reaction on the digested RS1 and RS2 amplicons. -Ran 1 uL of each on a 1% to quantify the amount of DNA present. -Ligated RS1 + pSB1A7, and RS2 + pSB1A7, using T4 DNA Ligase.
-1 uL of RS1/RS2 -4 uL of pSB1A7 -1 uL of 10x T4 DNA Ligase Buffer -0.33 uL of T4 DNA Ligase -3.67 uL of water
allowed the reaction to go overnight

Nathan Puhl
-Transformed DH5a cells with the pSB1A7 + RS1, and pSB1A7 + RS2 plasmids.
-Plated on semi-solid agar plates containing 100 ug/mL of ampicillin.
August 18
Christa, Nathan Puhl, Munima
-Nathan checked the plates for growth. Colonies are present.
-Ran a colony PCR of the pSB1A7 + RS1, and pSB1A7 + RS2 recombinant cells transformed by Nathan and Roxanne on August 17.
-Inoculated the cells into tubes of liquid media + 100 ug/ml of ampicillin.
Roxanne will remove the PCR tube from the thermocycler in the morning.
August 19, 2008
Roxanne
-Ran the PCR Product on a 2% Agarose Gel at 100 V for 33 minutes.
-Plasmid Prepped and made glycerol stocks from the RS1-1 and RS2-1 tubes of cells incubated in LB media + 100 ug/mL ampicillin.
Ran the pRS1 and pRS2 plasmids on 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.
August 21
Nathan Puhl, Roxanne
-Screened the pSB1A7 + RS1, and pSB1A7 + RS2 by PCR using the VF2 and RS1/RS2 Reverse Primers determine whether the plasmids obtained from the recombinant cells contain the riboswitch, and if so, if it inserted in the correct orientation.
August 21, 2008
Roxanne
-Ran the PCR products on a 1% Agarose Gel at 100 V for 33 minutes. The gel was empty with the exception of primer dimers.
Nathan Puhl, Roxanne
-went over the SELEX protocol with HJ to determine the primers we will need to do this, and how exactly we plan on perfoming the evolution.
-setup a restriction digest for pSB1A7 using XbaI and SpeI, ran overnight.

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.

-Digested pSB1A7 with Antarctic Phosphatase
-9 uL of cut pSB1A7 -1.5 uL of 10x Antarctic Phosphatase Buffer -1 uL of Antarctic Phosphatase Enzyme -3.5 uL of water Allowed the Reaction to take place for 30 minutes to remove the 5` Phosphates from the pSB1A7 plasmid to prevent religation.
