(In Lab: JV)

Objective: Isolate plasmid DNA of RBS-xylE (BBa_J33204) from DH5α cells and confirm results.

Method: "Mini-prep" the plasmid DNA using boiling lysis miniprep. Then restrict the DNA once and run on a 1% agarose gel (TAE).

DNA was restricted for 80 minutes at 37oC.

Analyzed results on a 1% agarose gel. Load order as follows:

† Added 9µL MilliQ H2O
†† Added 8µL MilliQ H2O
Ran gel at 100V from 2 hours.
Results:

Conclusions: Plasmid DNA prep and restriction was successful.

Objective: Ligate rbs-xylE (Bba_J33204) to our double terminator, and insert it into the pSB1T3 plasmid backbone.
Method:

  • Restrictions
    • Restrict rbs-xylE wit EcoRI and SpeI (Red Buffer)
    • Restrict the double terminator with XbaI and PstI (Tango Buffer)
    • Restrict pSB1T3 with EcoRI and PstI (Red Buffer)

    June 2/2010 - Evening

    Objective: Set up new ligations of pLacI and sRBS-Lum-dT according to Tom Knight's protocol. Previous ligation had very little DNA.
    Relevant Information:

    • Want a final mass of 25ng of each pDNA in the ligation mix.
    • Final concentration of pDNA in restriction digest should be 25-50ng/µL.
    • Tom Knight's restriction reaction is 50µL, therefore there should be 1000ng pDNA in each restriction digest.
    • Identified the following plasmids in our working plasmids box:
    Common NameLocationConcentration (ng/µL)Volume/rxn (µL)
    pLacI MaxiprepA9990~1
    pLacI (B1)A6440~2
    sRBS-Lum-dT (2)A1965~1
    sRBS-Lum-dT (1)A21145~1
    sRBS-Lum-dT MaxiprepB84780~.2
    sRBS-Lum-dTB74375~.25
    sRBS-Lum-dT (1)G2335~3
    sRBS-Lum-dT (2)G3965~2
    • Make a 1:10 dilution of sRBS-Lum-dt maxiprep (D8) and sRBS-Lum-dT (B7). 0.5µL pDNA in 4.5µL water.
    • Cut pLacI with EcoRI and SpeI
    • Cut sRBS-Lum-dT with XbaI and PstI
    • Cut pSB1T3 with EcoRI and PstI
    • Will have total of 12 ligation reactions, want 12x2µL of pSB1T3 to add to each, therefore want 25µL of pSB1T3.
