Charles:

  • Prepared o/n of UT2 (2 vials) and UT3 (2 vials) for a freezer stock

Andy:

  • Prepared o/n of UT3 BCDE for mini-preps
  • transformed and plated P0452 (2005) and P0456 (2005)

To-Do List:

  • Make freezer stock and minipreps of above tubes and check lengths along with P0352 (2005) and P0152 (2005)
  • Make more plates, autoclave tips, make more LB
  • Post up new protocols, include part length and resistance info in spreadsheet

Charles:

  • Made 22 competent cells
  • Tested Module 1 using varying concentrations of IPTG (0, 2, 20, 200, 2000 uM) to induce GFP (E0240 (2005)) and mRFP (I13507 (2005))

  • Data indicates that the GFP and mRFP as well as the LacI+ pL promoter (R0011) are functional (Does not indicate functionality of the pBad/AraC promoter and the inverter)
  • Some of the replicates seem to be outliers and if excluded, the regression increases significantly
  • DH5a-z1 are known to fluoresce, so the fact that untransformed cells glow brighter is not a big concern
  • Next step is to transform UT2 and UT3 into LacI negative cells then:
    • Characterize the fluorescence under varying Arabinose concentrations.
    • Vary the temperature to verify the temperature sensitivity of LacI ts and its affects on reporter expression

    </ul>

    To-Do List:

    • Post up new protocols, include part length and resistance info in spreadsheet
    • Make more plates and re-plate P0452 (2005) – AK, and P0456 (2005) – AC

    Natalie, Andy:

    • Prepared o/n growth of UT3 BCDE for mini-prep, DH5a for competent cells, and UT2 – 3,4,5, UT3 – 7,8,9 and DH5a x 2 (control) for making fluorescence measurements.
    • Checked lengths of miniprep UT2 ABCDEF, UT3 A (possibly unreliable due to 2 day o/n growth), P0352 (2005), and P0152 (2005).

    To-Do List:

    • Make 24 competent cells
    • Miniprep UT3 BCDE and test lengths
    • Make more plates and re-plate P0452 (2005) – AK, and P0456 (2005) – AC
    • Do measurements on UT2 and UT3
    • Post up new protocols, include part length and resistance info in spreadsheet

    September 18, 2006

    Charles:

    • Only mini-prepped UT3 A because they were grown for two o/n (Just want to see what happens)
    • Prepared new o/n for UT3 BCDE as well as 1 DH5a-z1, 2 UT2 and 2 UT3 for testing tomorrow. And 1 DH5a-z1 for making competent cells

    To-Do List:

    • Make 24 competent cells
    • Test the lengths of UT2 ABCEDF, P0352 (2005), P0152 (2005), and UT3 BCDE
    • Make more plates and re-plate P0452 (2005) – AK, and P0456 (2005) – AC
    • Prepare new o/n for UT3 BCDE – for mini-prep
    • Prepare o/n in the following quantities: 3 DH5a-z1, 3 UT2 and 3 UT3

    September 16, 2006

    Charles:

    • Made 4 replications of UT2 in 200 uM, 100 uM, 50 uM, 25 uM and 0 uM of IPTG.

      • OD of cells is too high, need to be <= 1.2
      • Need a control of untransformed DH5a-z1 to compare the relative fluorescence
    • Made frozen stock (2 vials each): UT01, I13507 (2005), B0015 (2005), B0031 (2005)
    • Mini-prepped UT2 ABCEDF, P0352 (2005) and P0152 (2005)

    To-Do List:

    • Test the lengths of UT2 ABCEDF, P0352 (2005) and P0152 (2005)
      • Prepare an o/n growth of the “best” UT2 for testing
      • Prepare an o/n growth of regular DH5a-z1
    • Mini-prep UT03 ABCD and test their lengths along with P00352 (2005) and P0152 (2005)
    • Re-plate P0452 (2005) - AK, and P0456 (2005) - AC
    • Make 24 competent cells

    Andy, Charles, Natalie, Stan, Elliott:

    • Checked and transformed I+J+I plasmids (Bands: ~6000-5000, 3500-2500 (smear))
    • Made competent cells (although, may have to repeat)
    • Prepared o/n growths of I+J+E (12 vials), P0152 (2005) and P0352 (2005). P0456 (2005) and P0452 (2005) did not seem to grow very well so left them in the incubator for a 2nd night
    • Made 8 Amp plates

    To-Do List:

    • Mini-prep P0152 (2005), P0352 (2005) and 6 of the I+J+E
    • Try to get J04450 (2006) working again.
    • Check lengths of R0011 (2005/6), if no good, then obtain R0010 (2005/6) from Registry
    • Make freezer stock (2 each) of I+J, B0015 (2005), B0031 (2005), and I13507 (2005) and put in -80C freezer stock
    • Test the fluorescence of I+J+E
