PCR

  • ran a gel of yesterday's PCR (62°C, magnesium gradient)
  • Gel is mostly blank except for 035
  • Looks like we didn't add polymerase and primers, but we certainly did
  • Possibly the change in temperature messed things up?
  • Will use 035C(2) in restriction digest to try to determine nature of the band

Restriction Digest

  • BstBI/BglII double digest
  • Should have 1 fragment at 333bp if we have GFP - AHI construct OR kan-ADH construct
  • Ran a gel of product. Weird: No apparent digest.

Gel Purification

  • PCR done
  • 2 MgCl gradients (0 and 2) at 58°C annealing
  • for 49, will try all 4 gradients (0, 1, 2, 4) at 55°C annealing
  • After running PCR, realized we mixed up primers/templates for 139 and 186; they were discarded.
  • Ran a gel; only got funky bands at 850kb; no actual product
Top: Ladder, -DNA, -Pol, 035, -, 49, 213, -, 236, 346. At 55C 41(0), 49(1), 49(2), 49(4)
Bottom: Ladder, -, -, 035, 49, 186, 213, 236, 346
  • must be a mispriming error, which is weird because they are supposedly no redundancies according to the sequence
