Riboregulators:

• 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)

Conjugation:

• 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)

Riboregulators:

• 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.

Conjugation:
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.
