    3. Add 600 uL (5X) PB (binding buffer) to sample
    4. Load sample onto column and spin for 1 minute at 14000 rpm; discard flow through
    5. Add 700 uL PE (wash buffer) to column and spin for 1 minute at 14000 rpm; discard flow through
    6. Repeat above step with 400 uL PE buffer
    7. Dry spin column for 2 minutes at 14000 rpm; discard flow through
    8. Transfer column to a new 1.5 mL eppendorf tube
    9. Add 40 uL TE to column
    10. Spin for 1 minute at 14000 rpm
  2. Size Select TBE Gel
    1. Mix 20 uL sample and 4 uL 6X dye per sample
    2. Mix 16 uL TE, 4 uL ladder, and 4 uL 6X dye per sample
    3. Aliquot 24 uL for each sample/ladder into a separate tube
    4. Mix and add 23 uL per lane to gel
    5. Run gel at 230V for 24 minutes
    6. Add 2 uL SYBR gold and incubate on shaker for 3 minutes
    7. Rinse and image in gel doc
    8. Cut out bands at approximately 221bp
    9. Add extracted gel bands to 0.5mL tube with 0.2 gauge needle hole inside a 1.5 mL tube
    10. Centrifuge for 1:30 at 13000rpm
    11. Throw away 0.5mL tube and add 500 uL TE buffer to each tube
    12. Incubate at 37C for 1 hour
    13. Centrifuge for 1:30 at 13000rpm
    14. Withdraw supernatant and add it to a nanosep column
    15. Centrifuge for 1:30 at 13000 rpm
    16. Remove flow through and add it to new 2 mL tube (~500 uL)
  3. Ethanol Precipitation
