F2620 Expression Protocol
- Create Liquid Cultures in LB Media
- Dilute Back 1:500 in LB Media
- Grow up for an hour in warm room roller
- Split culture in two
- Add AHL to one culture to a final concentration of 1E-6M
- Grow up for 4 hours in warm room roller
- Spin Down, Decant, and Resuspend in PBS
- Measure absorbance at 600nm and red fluorescence level
See characterization data for BBa_F2620.
Today's Agenda
- Redo Overgrown Liquid Cultures
- Send for Sequencing
- Cut CPX and Backbone for ligation
- Start designing high copy backbone
- PCR off relevant portion of Mer operon from pto40 - Done
- Organize fridge - Done
- Design and order EC_20 Insert
- Email Isadora + Tom Knight for Meeting Times--Toan--Done
- Anneal FHUA Insert oligos - Done
- Understand Meinke Inducible System
Status of Expected Parts
- IDT Primers + Inserts - Arriving Today--ARRIVED
- CPX - At FedEx Facility in Boston
- FhuA - ARRIVED
Sequencing of LC#1&2 from 3A
- Miniprepped LC's of those colonies that grew only on Kan plates and not on Kan/Amp plates
- Sent in 4 samples, one forward and one reverse for each LC
- used 4µl of DNA since each was approximately 30ng/µl
- Order Number 8046
Dilution of Ordered DNA
- Made 100uM stocks of all IDT primers and single-stranded inserts
- Diluted 100uM stocks of primers/inserts into working stocks of 10uM concentration
Annealing Complementary Primer Inserts
- 10 uL of 10 uM of oligo
- 2 oligos - total volume 20 uL
- Mix with 80 uL water
- PCR Thermocycler Temperatures
- 95 C
- Ramp down
- 0.1 C/sec
Phosphorylation of Primer Inserts
- 20 ul Annealed Oligo
- 4 ul T4 DNA Ligase Buffer
- 2 ul PNK (Kinase)
- 14 H20
- 37° - 1 hr, 65° - 20 mins
Digestion of FhuA backbones
- used PCR Purification kit to purify backbone
Nanodrop of FhuA inserts/backbone
- PICCS5 - 10ng/ul
- PHIE6 - 5ng/ul
- Insert- 650 ng/ul - instead just use rule of thumb .5 ul/20ng backbone
Ligation of FhuA inserts/backbone
- Mix 1: PHIE6
- .5 ul Ligase
- 2 ul Ligation Buffer
- 1.5 ul Insert
- 10 ul Backbone
- 6 ul H20
- Mix 2: PICSS5
- .5 ul Ligase
- 2 ul Buffer
- 1.5 ul Insert
- 5 ul Backbone
- 11 ul H20
