===Notes for Jeff:===
Look on yesterday for the results of running J04500 longer; the undigested band didn't run as fast as the others, so I don't quite trust that gel... it's sitting in the fridge at our bench if you want to extract anything. Sorry I didn't get a change to gel purify the KaiA,B,C, though 6 tubes with the gel pieces are sitting in the green holder in our fridge; if you guys have time, try to purify it today. Otherwise, let's see how this digest runs; and we will definately need to do a ligation for J04500 with our gel purified KaiABC tonight.

Yet another digest attempt

From our previous gel, it can be argued that the J04500 digest was inconclusive and that the KaiA,B,C digests were poor. Looking back on previous results, the first digest I ever did seemed to be the cleanest one run and gave a working ligation; I'm posting the results of that digest below. The protocol is virutally the same though and we redid this digestion a couple of days ago at varying time pts.... what could cause the diff. results?

Here is a digest attempt using 45C: http://www.neb.com/nebecomm/products/faqproductR0133.asp#850 says it causes an increase in activity...

What Dave and I did before (6/14)

  • Digestion of vector/insert
    • Digested R0010 (200bp cutout) as vector at S and P site.
      • .5uL Spe1, .5uL Pst1
      • 11uL h20
      • 2.5uL 10X BSA
      • 2.5uL #2 NebBuffer
      • 8uL DNA
    • Digested other 2 (~900bp cutout) as insert at X and P site.
      • .5uL Xba1, .5uL Pst1
      • 11uL h20
      • 2.5uL 10X BSA
      • 2.5uL #3 NebBuffer
      • 8uL DNA
    • Incubate @ 37C for 1h
  • Phosphatase
    • 80C@15min to kill enzyme activity
    • Used CIP (1 unit) into the R0010, 1h@37C
  • Run on 1% agarose gel
  • Image, Cutout, and Purify
    • Can isolate the three from the gel
