Library Prep

  1. Qiaquick Purification
    1. Combine samples A+B for each condition into a 1.5 mL tube
    2. Add 600 uL (5X) PB (binding buffer) to sample
    3. Load sample onto column and spin for 1 minute at 14000 rpm; discard flow through
    4. Add 700 uL PE (wash buffer) to column and spin for 1 minute at 14000 rpm; discard flow through
    5. Repeat above step with 400 uL PE buffer
    6. Dry spin column for 2 minutes at 14000 rpm; discard flow through
    7. Transfer column to a new 1.5 mL eppendorf tube
    8. Add 50 uL TE to column
    9. Spin for 1 minute at 14000 rpm
  2. Size Select TBE Gel
    1. Mix 30 uL sample and 6 uL 6X dye per sample
    2. Mix 26 uL TE, 4 uL ladder, and 6 uL 6X dye per sample
    3. Aliquot 36 uL for each into a separate lane
    4. Run gel at 230V for 24 minutes
    5. Add 2 uL SYBR gold and incubate on shaker for 3 minutes
    6. Rinse and image in gel doc
    7. Cut out bands at approximately 221bp
      • Note that this is a pretty bad gel, so I had to take wider fractions than I would have liked. We'll see how the sequencing results look
    8. Add extracted gel bands to 0.5mL tube with 0.2 gauge needle hole inside a 1.5 mL tube
    9. Centrifuge for 1:30 at 13000rpm
    10. Throw away 0.5mL tube and add 500 uL TE buffer to each tube
    11. Incubate at 37C for 1 hour
    12. Centrifuge for 1:30 at 13000rpm
    13. Withdraw supernatant and add it to a nanosep column
    14. Centrifuge for 1:30 at 13000 rpm
    15. Remove flow through and add it to new 2 mL tube (~500 uL)
  3. Ethanol Precipitation
    1. Add 1250 uL 100% EtOH, 50 uL 3M NaOAc, and 1 uL glycoblue to each tube
    2. Incubate overnight at -80C
