1) 2μL sheared Greenbul DNA,
2) 2uL 100bp low scale ladder,
3) 2uL sheared Sunbird DNA
2015-02-02:
- Blunt End Repair
- Mix:
- 50.0 uL fragmented DNA
- 5.5 uL water
- 3.0 uL End Prep Enzyme Mix
- 6.5 uL End Repair Reaction Buffer
- Incubation (NEBENDRP on JOHN Block B):
- 20 degrees for 30 minutes
- 65 degrees for 30 minutes
- P2 adapter ligation
- Add to mix:
- 15.0 uL Blunt/TA Ligase Master Mix
- 2.5 uL P2 RAD adapter (5 uM)
- 1.0 uL Ligation Enhancer
- Incubation (NEBLIGAT on JOHN Block B):
- 20 degrees for 15 minutes
- Size selection
- Add 16.5 uL water for a total of 100 uL
- AMPure bead size selection:
- 45 uL beads to remove large fragments
- 25 uL beads to remove small fragments
- 3 washes of 200 uL 80% EtOH
- Elute in 20 uL LowTE
- PCR amplification
- Mix:
- 5 uL DNA
- 25 uL NEBNext High Fidelity 2x PCR Master Mix
- 18 uL water
- 1 uL P1 adapter primer (25 uM)
- 1 uL P2 adapter primer (25 uM)
- PCR cycle (NEBPCR on JOHN Block B):
- 98 degrees for 30 seconds
- 15 cycles of:
- 98 degrees for 10 seconds
- 65 degrees for 30 seconds
- 72 degrees for 30 seconds
- 72 degrees for 5 minutes
1) 1μL Greenbul DNA template, 2) 5μL Greenbul PCR product, 3) 2 uL 100 bp low scale ladder, 4) 1μL Sunbird DNA template, 5) 5μL Sunbird PCR product
→Greenbul PCR does not look brighter than template, but may not be half as bright. Also, gel ran twice because first one failed, leaving only 40μL of PCR product left.
2015-02-03:
- Re-run PCR amplification
- Mix:
- 10 uL DNA
- 25 uL NEBNext High Fidelity 2x PCR Master Mix
- 13 uL water
- 1 uL P1 adapter primer (25 uM)
- 1 uL P2 adapter primer (25 uM)
- PCR cycle (NEBPCR on JOHN Block B)
1) 1μL Greenbul DNA template, 2) 5μL Greenbul PCR product, 3) 2 uL 100 bp low scale ladder, 4) 1μL Sunbird DNA template, 5) 5μL Sunbird PCR product
Because Greenbuls did not seem to amplify well, proceeded with Sunbird library only:
- Bead clean up
- Use 45 uL AMPure beads (1:1)
- 2 washes of 200 uL 80% EtOH
- Elute in 30 uL LowTE
- Quant DNA library using Qubit HS: 9.6 ng/μL
- Run 1μL library + 2μL H2O on BioAnalyzer DNA High Sensitivity Chip (2015-02-06)
- Dilute library to 10 nM in 10 uL and send to Berkeley for sequencing (Illumina HiSeq 100 SR) (2015-02-09)
