Revision as of 16:32, 8 November 2016
M2D1
Per group, aliquot
- 30 μL nuclease-free water
- 5 μL pdCas9 (ideally at 500 ng/μL)
On front bench, have
- restriction enzymes in -20 °C block
- NEB buffers
- list of 20.109-owned restriction enzymes
Fa16: all done by 5pm
M2D2
Per group,
- pour 1/2 agarose gel (only 5 lanes needed)
- thaw 4 samples of confirmation digests
- aliquot 10 μL of 6X loading buffer
- thaw 20 μL of 1 kb ladder
Call IDT to request expedited FedEx shipping of gRNA oligos.
Fa16: all done by 4:30pm Should schedule BE Comm Lab workshop on Journal Club on this day.
M2D3
On ice,
- 1.2 mL aliquots of nuclease-free water
- reverse primer at 100 μM
- psgRNA template
- HotStart Master Mix
- -20 °C block for PCR tubes
- strip of PCR tubes with colors (+1 for control)
- SDM control primer mix
- SDM control plasmid
Also on front bench,
- filtered tips
- gRNA forward primers received from IDT
The thermocycling program is called NEBSDM.
Later, on ice
- KLD reaction buffer
- KLD enzyme mix
- NEB5α cells (1 per group + 1 for control)
- LB+Amp plates (1 per group + 1 for control)
M2D5
The day before lab (8pm), inoculate 2 colonies per team.
Aliquot, per team:

- P1 (600 μL)
- P2 (600 μL)
- P3 (800 μL)
- PB(1100 μL)
- PE (1600 μL) of buffer PE
- water pH 8.0 for elution (50 μL)
- 2 mini-prep columns
- MG1655 competent cells (100 μL), on ice late in the afternoon
- SOC (1 mL)
- 2 LB agar plates +Amp+Cam
- burner + lighter + spreader + jar of ethanol
On front bench,
- students plates of pgRNA
- water bath at 42 °C
- sequencing F and R primers at 5 μM
- nuclease-free water
- PCR tube strips for sequencing

- 15 mL conical tubes (4)
M2D8
On front bench, per team:
- cuvettes for spectrophotometer (9)
- conical tubes (4)
- eppendorf tubes (16)
- on ice: for kits
- standard
- substrate
- enzyme
Aliquot, per team
- LB (20 mL for ethanol, 10 mL for lactate)
- PBS (none for ethanol, 4 mL for lactate)
- assay buffer (4.5 mL for ethanol, 4 mL for lactate)
