Restriction Restricted parts with respective restiction enzymes
Made a 1X TAE Agarose Gel stored in fridge overnight.
Ran Agarose Gel from September 8th.
Gel extraction went well all pieces showed up with the exception of J04500-Enhansed Lumazine in pSB1AK3
Set up ligations of
Assembly of Ptet-Rbs in pSB1A2 to have XylE- ATag-Dt Did a restriction Digest, Cutting pTet-rbs with SpeI and PstI Restricted XylE Atag- dt with XbaI and PstI While the Restricted at 37 degrees Celcus for 1 hour made a 1% TAE Agarose Using TAE from Weiden stocks for both Gel and buffer. Loaded gel with samples and ran at 80Volts for 60 minutes. Was very happy to see the gel running at normal Amps and reaching regular Volts, No more melting Gels!! Gel analysis by UV indicated Restrictions did not work for XylE
3 days back and nothing has worked, Persistence is the only way Were going to get through this!! Build a new copy of Xyle + S04261 Since the stock copy is unaccounted for/Incognito. Found Prerestricted Xyle and S04261 in team ones book, and located in freezer, Performed a ligation, left overnight. Restricted Enhansed Lumazine Synthase-Dt in pSB1C3 cut at EcoRI and XbaI to later ligate with previously restricted J04500 cut at EcoRI and SpeI Also Restricted, J04500 out of pSB1AK3 by cutting at EcoRI and SpeI to be ligated with the Enhansed Lunazine synthase-dt in pSB1C3 Also Restricted Enhansed Lumazine Synthase in pSB1C3 at sites SpeI and PstI and Dt D6 was restricted at XbaI and PstI. ( later to learn should have left Dt in plasmid and removed the enhansed Lumazine synthase, Dt was too small and ran off gel.
Ran all parts on a 1% TAE agarose Gel,
Ligated each of the Enhansed Lumazine Synthase-Dt with The Gel restricted J04500 and the previously restricted J04500
Transformed and plated cells left in incubator overnight
End of the first Week worth of classes, and still nothing grows/ works Why?? I am informed I am using the wrong enzymes, a type that wont heat kill, ( later questioned, but im running a gel for extraction, Does this still matter? Since I was informed the heat kill process doesn’t need to be done when running a gel for extraction, When I was introduced to the gel extractions, I asked why are we doing it this way, the answer was ‘It’s more efficient!’ apparently in theory only) Ok one More Kick at it, New enzymes check, Proper TAE check, advice from Phd students Check, Objective: Get something to work, Feeling I have it all figured now, I set forth once more.
Made Gel while Restrictions incubated,
Stored restricted DNA in Freezer overnight to be used in gel in the morning,
Gel froze overnight in fridge, so Made two new gels 1 small one large both 1% TAE Agarose ( so much for loading a gel and going to class) Added loading dye to samples and ran on gel, Ran gels at 80Volts for 90 minutes Enhansed Lumazine Synthase –dt did not work restriction issue J04500 –Enhansed Lumazine synthase did not work restriction issues XylE –ATag-Dt was not run on gel, portion too small for successful gel extraction/ not enough lanes, Only Enhansed Lumazine and Dt D6 in pSB1A2 were available to proceed to gel extraction, Limited number of Spin columns available, Gel Extraction Failed Wrong product poured into wrong spin column
