  3. Put on ice and add 1.5 uL NS --> 3uL NS
  4. Pol I Master Mix (Total 20 uL)
    • Template 4 uL --> 7 uL
    • 10x NEB buffer 2 (NEB) 1 uL
    • 10x ampligase buffer (Epicentre) 1 uL
    • dNTP (Epicentre) 0.4 uL
    • N6(unmodified) 1 uL
    • H2O 11.6 uL --> 8.6 uL
    • PolI (Invitrogen) 1 uL
  5. 37 C for 1 hr min, pause
  6. Add 0.2 uL ampligase and 37C for 10min, and 65C for 10min
  7. Standard EtOH precipitate and elute in 4 uL water

  6. Add 750 uL of 75% EtOH
  7. Spin at 10krpm for 5min at 4C
  8. Remove supernatant (pipette 700 uL first --> 200 uL pipette last)
  9. Elute with 7 uL H2O


Tagmentation[edit]
