Andy, Charles, Melinda, Natalie, Ram, Siva, Tara:

  • Made new agar plates (amp = 5, kan = 5, amp/kan = 5)
  • Made o/n of UT2 (5), UT3 (5) and DH5a
    • UT2:
      1. Plate BA, colony 20
      2. Plate BB, colony 21
      3. Plate CA, colony 22
      4. Plate CA, colony 23
      5. Plate CB, colony 24
    • UT3:
      1. Plate AB, colony 25
      2. Plate BB, colony 26
      3. Plate BB, colony 27
      4. Plate BC, colony 28
      5. Plate CC, colony 29
    • Also made o/n for UT2 (2), UT3 (2) from freezer stock
  • Transformed I12006 AB (2005)
  • Digested and checked lengths
    • I12006 ABH (2005): (5000 – 4000) – correct
    • UT1 AB: (5000 – 4000, 3500 – 3000) – correct
    • UT2 EF (3000 – 2500, 1000 – 750) – not so correct
  • Digested I12006 AB (2005) with SpeI/PstI and E0240 EF (2005) with XbaI/PstI
    • I12006 ABH (2005): (5000 – 4000, 2000 – 1500) – not so correct
    • E0240 EF (2005): (3500 – 3000, 2500 – 2000, 2000 – 1500, 1000 – 750) – not correct
    • Did not gel extract I12006 and E0240

To-Do List:

  • Try different ligation enzymes, thus ligate UT4 with I12006 then ligate with E0240.
    • Digest I12006 AB (2005) with EcoRI/XbaI (host) and UT4 AB with EcoRI/SpeI (insert)
  • Check UT2/UT3 under microscope to find out if we have fluorescence
    • If we do, mini-prep the o/n and transform cells
  • DH5a vs. [Arabinose] to test potential arabinose induced fluorescence reduction
    • Use PBS + Arabinose as a reference

October 11, 2006

To-Do List:

  • Digest I12006 H (2005) and I12006 AB (2006) with XbaI/SpeI and check lengths
  • Transform cells with I12006 AB (2005)
  • Transform cells with UT1 AB, UT2 EF, UT4 AB
    • Try to find the UT4 used to make a measurement (that was successful)
  • Digest I12006 AB (2005) with SpeI/PstI
    • Ligate I12006 AB (2005) and E0240 (purified DNA from Oct4)

Long-Term Goals:

  • Once the mini-preps of the correct lengths are obtained, retest UT2/UT3 with increasing IPTG to repeat previous experiment (if successful, take pictures)
  • Need to test to see if arabinose is having deleterious effects on fluorescence
    • DH5a auto-fluorescence vs. [Arabinose]
    • Consider using a tetR promoter instead of pBad/araC
  • Do an Arabinose and IPTG surface response test to find optimal concentrations
  • NOTE: try not to overgrow the cells – signal seems to saturate quickly

Anne:

  • Prepared DH5a UT2 for LacI temperature test
  • Mini-prepped I2006 H (2005) and I12006 AB (2006)

Cheng:

  • Prepared DH5a-z1 UT2 for IPTG induction of GFP

Conrad:

  • Re-test UT4C, UT5 ABC and I12006 EFG (2005) with XbaI/SpeI
  • Miniprep UT2/3 in DH5a

Siva:

  • Prepared DH5a UT2 for Arabinose induced LacI test

Recorded digest length check results:

  • I12006 EFG (4000-5000, 1500-1000)
  • UT5 ABC (3500-4000, 750-1000)
  • UT4 C (3000-3500)
  • UT3 DH5a (750-1000, 2000-2500)
  • UT2 DH5a (750-1000, 2000-2500)

Test Results

October 6, 2006

Andy, HoKwon:

  • Prepared o/n (3 vials each) of DH5a and DH5a-z1 with UT2 and UT3 for testing
  • Prepared o/n of UT2 DH5a and UT3 DH5a for miniprep
  • Transformed and plated I12006 (2005) (poured in amp plate first by accident), I12006 (2006)
  • Double Digest parts E0240 CD (2005), UT4 AB with XbaI/SpeI
    • E0240 CD (2000-2500, 750-1000) Correct!
    • UT4 AB (3000-4000) Correct!

Charles, Cheng, Nick:

  • Re-tested UT4 C, UT5 ABC – failed due to a very dry gel

  • Gel extracted E0240 (insert) and UT4 AB (host)
  • Transformed and plated DH5a with UT2/UT3 for testing
  • Made o/n of UT2/UT3 with IPTG

To-Do:

  • Learn to take fluorescent images under microscope
  • Temperature testing
  • Try ligating UT5 again
  • Running out of water and PCR tubes
