I ran Sam's gel of J23074 and J23075, but overran it. They all looked much better than when we transformed into TG1--all gave normal bands, no extra bands, all samples were mostly similar. Note that the correct sequences of things are:


(They aren't both pSB1AK3).
100206-Berk2006-gel.jpg I remapped clone 1 of each and set up the EcoRI/SpeI digests to transfer things to pSB3C6 (above) The lanes go:

pJ23019 (ES)
pSB1AK3-J23074 (ES)
pJ23019 (ES)
pSB1A2-J23075 (ES)
pSB1AK3-J23074 (AvrII/AlwNI)
pSB1A2-J23075 (AvrII/SpeI)

The J23074 clone 1 is correct, and I cut the slices to do ligations. J23075 was wrong, we need to remap the other 3 clones.


  • Miniprepped J23074 and J23075, digested in AvrII and SpeI to map
  • Miniprepped pSB1AG0-J23038s, and sent them for sequencing
  • Results from conjugation assay:

J23057xJ01003 on TriA ---- has >1000 colonies, is problematic because supposed to have a lot less efficiency since traG is knocked out
J23057xJ01003 on TriK ---- no colonies, which is good
J23055xJ01064 on TriA ---- only 4 red colonies on plate after a 1 mL dilution - good results
J23055xJ01064 on TriK ---- no colonies, good

  • plate of pJ23006-J23086 key3.oriTr looks good. need to grow up cultures and miniprep eventually


  • Genomic mini of j23016
  • PCR j23016 with JL16 and JL17 for D/W
  • mate J23055/J01064, mate J23057x1003
  • resub key3.oriTr - jen said pJ23006-J23006 but actually pJ23006-J23066 and J01003
  • grow up two clones of pSB1AG0 - J23038 , 4 clones of pSB1A2-J23074 and pSB1A2-J23075 each (Maybe John will do the growing up tomorrow so that they will be fresh on monday )


  • Mini, map, J23074 and J23075 - the gel came out pretty crazy, none look right
  • move to pJ23018 (ES)(p15A version ofTraG) when ready) - digested it today
  • (Transform J23016 x pSB1A2-J23075 (Show we can rescue TrbC function))
  • Religate J23074 and J23075 and put them into DH10B instead
  • Subclone J23038 with Gen marker in front)
  • Sub the key3.oriTr with pJ23006 and J01003
  • Grow to gen prep J23016 (trbC KO, CmR)
  • Grow to D/W J23055 #1 (OriTf KO) /pKD46 (x trbC cass)
  • Grow to test mate J23055/J01064 (OriTf) (Show we can move transfer function to new plasmid)
  • Grow to test mate J23057/1003 redo (later x pAC-traG) (Same as above but in the R system)


  • resub J23074 and J23075
  • map pSB1AG0-J23078 (the analytical digest is in the incubator)
  • comp J23055 #1 from starter x pSB1A2-J01064, and xpkd46 (30degrees)


  • made competent cells of Rlam/J23057
  • transformed pSB1A2-J01003 into Rlam/J23057
  • Subcloning pSB1AG0-J23078 by digesting pSB1AKG0-b0015 (small) and pSB1A2-J23078 (big) in E/X to drop the Gen marker from b0015 into J23078. Got up to the digestion clean up step - ligation and transformation left to do.
  • Ran a gel from the analytic digests of J23074, J23075, J23026, J23028. They came out negative and inconsistent
  • gel on PCRs of J23055 (2 clones) - clone 1 showed a band, clone 2 did not
  • replate to comp J23055 clone#1 on Kan (transofrm J01064, pKD46 later)
  • Colony PCR J23075 and J23074


  • grew up cultures for tecan for J23077xJ23066 assay including J23077 from -80
  • ran a gel on PCRs for traGr knockout strain


  • miniprepped and made a -80 of pSB1AT3
  • miniprepped J23028 (running low)
  • Grew and spotted MC1017C from CP20 and J23069 from CP20 on Amp and Cam
  • Grew up 4 clones of pBCa1020-J23038
  • Grew up 4 clones to screen of pSB3C6-J23077 and pSB1A2-J23078
  • made LB stabs and LB-Carb plates
  • Scraped J23015-pCP20 and grew a culture in LB only

We got sequencing for J23072 clone 5 (iG139), it is correct. The cells were visibly pink, so we aren't pursuing this further. Putting the "correct" spacing between the rbs and start codon seems to bump the background in J23071 and J23072 too high. The tecan data for J23071 was:

TG1 50
1122 60
1122/1129 90
1022 6563

J23071 367
J23071/1129 272
J23071/J23066 844

Going to focus instead on J23077 (and J23078, the basic part), which are lock3d variants with the 5' extension.


  • PCRed pJ23006-J23032 and pJ23019-J23049(aka pSB3C6-J23032) for later construction of J23077 and J23078
  • ran a gel for a bunch of PCRs of J23074 and J2307



  • transformed J23075 clones 1 and 2 into J23016 for Jen (plated on Amp)
  • assayed J23071x1129 and J23072x1129 - the J23071 looked promising, almost 10% fluorescence as the OnRFP, the J23072 was obviously wrong, because flurorescence was even lower than the lock by itself and the TG1 cells.
  • J23072 could have a pink phenotype and too high of a background to use. Grew up another 4 colonies of J23072 to screen.
  • Grew up tecan cultures J23071 only and J23071x1129 to check the background versus gain for j23071. (Chris will do the tecan tomorrow)
  • digested pJ23076 with SpeI/PstI, the backbone to make J23073 with a PCR on j23072 just in case that does end up working in the future. Ran a gel and cleaned up the digested product. (In cardboard riboregulaters box)
  • co-transformed pSB3C6-J23071 (best lock so far) and pJ23006-J23066-1 (best key so far) into TGI cells to see what happens before proceeding with J23071 and adding a 5 prime end.


  • grew up tecan cultures


  • culture of pSB3C6-J23072 clone #1 was slightly pink, so I proceeded only with clone #2 which was white and should be correct.
  • Miniprepped, made a -80, and sequenced pSB3C6-J23072-2. Also threw out pSB3C6-J23071-1 from -80 stocks, because clone 2 was the right one.
  • transformed J23072-2 and J23071-2 into J01129 (Chris will put plates in fridge tomorrow)
  • all cultures of pSB3C6-I13521 appear white, even after pelleting, they still look white, so something must have gone wrong. Will remake later.
  • made a bunch of LB Agar and LB Broth (Reza and Melissa will autoclave for me)


  • grew up two white colonies of pSB3C6-J23072
  • sequencing for J23071 clone#2 looks good and is in the -80
  • pSB3C6-I13521 plate has all white colonies it seems unfortunately. Growing up four clones just in case they turn pink in culture.

For Friday:

  • miniprep clones of pSB3C6-J23072, make -80s, and send them in for sequencing
  • transform J23072 and J23071 into J01129
  • Pick colonies Sunday and Assay on Monday



  • cultures of new locks J23071 and j23072 look a little red. Miniprepped 2 white cultures of pSB3C6-J23071, made -80 stocks of them, and sent them for sequencing with ca1000. Pick colonies of J23072 again when we get back from the break, plates are in the fridge.
  • ligated and transformed pSB3C6-I13521. (John will put in fridge tomorrow)


  • purified the PCR product of pSB1A2-J23038 and digested with BsaI/SpeI/dPN1, then purified again.
  • digested pSB1AK3-J23026 (traG+TT) and pSB1AK3-J23028 (trbCf+TT) with BsaI/XbaI, ran gel and gel purified.
  • ligated and transformed to get products pSB1AK3-J23074 ([pCon][RBS][traGr][TT]) and pSB1AK3-J23075 ([pCon][RBS][trbCf][TT]). (John will put in fridge tomorrow)



  • grew up 4 white colonies each of new locks J23071 and J23072.
  • Started to make pSB3C6-I13521 to replace pSB3C6-J01022, which just removes the upstream Ptet to do future measurements relative to a more-similar standard. Made a construction file and cleaned up digestions of I13521 and pAC997 (found in "Good" Plasmids box). Ligate and Transform tomorrow.
  • sequenced pJ23006-J23070 #1 and pJ23006-J23062 #1 (the tRNA-based keys)with ca998.

Finishing up the traG and trbC complements

  • PCRed pSB1A2-J23038 with G00101 and ca641R to get the short pCon+RBS fragment. Tomorrow, digest this fragment with BsaI/SpeI/dPN1. Also, digest pSB1AK3-J23026 (traG+TT) and pSB1AK3-J23028 (trbCf+TT) with BsaI/XbaI. Purify, ligate and transform to make new pSB1AK3 complements. Make construction files. BsaI is not in the APE enzyme list it is GGTCTC.
