To-do

  • Midiprep
    1. Midiprep pSB4A3, J04500 (online instructions here, page 16) (in progress)
  • Insert:
    1. Digest miniprepped KaiA/B/C in GeneArt vector with X-P (in progress; 2 hr digest finishes at 7PM, 4 hr finishes at 9PM)
    2. Gel-purify
    3. (maybe) Inoculate more KaiA/B/C in GA vector
  • Backbone:
    1. Digest J04500\S-P, \X-P (for Stage I constructs and BB high-copy) (in progress; 2 hr digest finishes at 7PM, 4 hr finishes at 9PM)
    2. CIP treatment of the above
    3. Gel-purify the above
    4. Find and transform B0034
  • KaiABC ligation:
    1. KaiABC\X-P + J04500\S-P (stage I)
    2. KaiABC\X-P + pSB1AK3 (well-formed BB) (we can purify this backbone from the J04500\X-P digest)
    3. KaiABC\X-P + B0034\S-P (stage I)
  • Sequencing:
    1. Sequence miniprepped KaiA/B/C + GA vectors, natural KaiA
  • Western blots:
    1. Ligate GFP dev\X-P and pSB4A3\S-P, transform (Wait until we've midiprepped more pSB4A3 and do another digest, because the pSB4A3\S-P from our digest assay was a curious size)
    2. Inoculate GFP dev + pSB1A2

It appears that our vector self-ligated.

Add 5.5 µL of the corresponding master to each tube.

Transformation of B0034

We transformed B0034 (the Elowitz RBS) for use in one of our constructs. We plan to ligate it with KaiC for several of our Stage I experiments.

B0034 was rehydrated in 15 uL H2O and placed in the "Rehydrated Biobricks" container of the -20C freezer in the gel imaging room.

The part is on a pSB1A2 vector.

Transformations:

  • 30 uL Top10 competent cells, 1 uL B0034
  • 20 uL Top10 competent cells, 1 uL H2O (negative control)

Plates:

  • B0034 in pSB1A2 in Top10 #1 (20 uL of SOC medium plated)
  • B0034 in pSB1A2 in Top10 #2 (rest of SOC medium plated, ~260 uL)
  • H2O in Top10 (50 uL plated) (negative control)

Inoculation of GFP device

We inoculated 5 mL of LB-Amp with GFP device from frozen stock. This will be used in preparation for tomorrow's Western blot tutorial.
