Jeff, Mackenzie, Ashley

Using 1/10 and 1/100 dilutions of pTET and EYFP to perform large scale digests.

  • pTET:PstI and SpeI
  • EYFP:XbaI and PstI

4 reactions each:

  • single digest (PstI/SpeI and XbaI/PstI)
  • double digest
  • no digest

100µL each, means we need 400µL total for each.

1/10 dilution=40µL DNA, 360µL water

1/100 dilution=4µL DNA, 396µL water

Reaction set up:

  • 88µL DNA

  • 1µL RE1 (or water)
  • 1µL RE2 (or water)
  • =100 µL total

Only 9/18 transformations worked

Success:

  • mmS6 in pSB1A3
  • mmS6 in dT
  • riboswitch in pSB1A3
  • CheZ in dT
  • CFP (no promoter)
  • GFP gene
  • pSB1A3 + n-term EFYP (1)
  • pSB1A3 +n-term EYFP (2)
  • fused c-EYFP

Added more ligase and will re-transform the following:

  • Fused NEYFP (1)
  • Fused NEYFP (2)
  • Fused NCFP (1)
  • Fused NCFP (2)
  • Fused CEYFP
  • Fused CCFP

  • pSB1A3 +N-CFP (2)
  • pSB1A3 +C-CFP (1)
  • pSB1A3 +C-EYFP (1)

Transformed all of the above. Picked colonies of successes.

Aug 15th

The transformations didn’t work! Restart

Picked 3 colonies of cheZ-dT

1 of mmS6+dT (for mini and maxiprep)

3 of fused C-EYFP

3 of pSB1A3-mmS6

3 of riboswitch in pSB1A3

3 of GFP gene

3 of CFP (no promoter)

2 of the riboswitch and all of the N-EYFP in pSB1A3 turned red suggesting that the RFP reporter was religated in.

Will miniprep the “good” cells and restrict with EcoRI to check for size

Pelleted down cells (small samples and large samples) picked from transformations to prep for mini-preps.

Add 750 x2 micro liters of your small sample solution to centrifuge tube, Add 50 mL of large sample to large centrifuge tubes. Balanced the Centrifuge and ran for 2 minutes at 13000 rpm. Dump out Supernatant/ leave pellet. Add more sample, centrifuge, and remove more supernatant. Add remainder of sample, centrifuge, remove supernatant. Left samples in -20 degree freezer.
