General
- Prepare antibiotic aliquotes
Preparing the parts
-
Sequence the lysis cassette -
Double-check lysis cassette sequence
All the parts are verified, we can now assemble them!
Assembly
Plasmids
-
Research plasmid backbones. Is there one that already contains Tet-repressed LacI or GFP? -
Design Gibson primers to assemble the three different plasmids. -
Receive said primers - Determine which sequence on LacI-plasmid and Lysis-plasmid should be used to create the "mega-plasmid".
- Think of new assemblies we want to make (pTet with RFP, for example)
- J61002 plasmid:
-
adding pTet: OK - adding tetR with const promoter: primers ordered
- adding LacI under Ptet + RFP under Plac: cells transformed
- adding LacI under Ptet + lysis cassette under Plac: cells transformed
-
- J23019 plasmid: pcr failed so far -> test new plasmids for the LacI plasmid
- pSB3C5: glycerol stock, primers ordered
- pSB3K1: glycerol stock
Specifically:
- Run PCRs and gels on existing sequences (plasmid backbone, TetR gene, RFP)
TetR mutants
-
determine required sequences -
order primers - Mutation-inducing extension PCR for MITOMI:
- Possibly rerun PCR; until decent results are obtained for all 6 mutations
- Extract by gel purification
MITOMI
For wtTetR
-
repeat MITOMI with wtTetR His-tagged (linear template) and wtTetR GFP-tagged (plasmid), for consensus and negative control sequence. DNA spotted in different concentrations - experiment with de Brujin library spotted on His-wtTetR or/and wtTetR-GFP (this will yield PWM)
experiment planned on July 6
- 1-off library on wtTetR linear template
Further, check the ordered muTetRs (determine position weight matrix)
- determine position weight matrix for muTetRs, compare with de Brujin results
Microfluidics and chemostat chip
- Continue alignment training
- Repeat experiments to check design
- Grow E. Coli from spotted arrays
-
[No microfluidics] Setup a plate and test tween concentrations -
Determine growth rate as function of tween concentration (say 0.075% +- 0.7, as many increments as will fit on the chip) - Adapt design of "chemostat" chip for e-coli
Wiki
Protocols
-
Describe cell cultures in miniprep protocol - Create protocol Template, with "Back to protocols" link at top
- Include an easy printing option
- Write a new protocol!
- Upload "chemostat" protocols
General
- Write-up team presentation
- Upload our initial research about transcription factors
Clean room
- Order lab notebook
-
Order storage box
