Program

  • 95C 30sec -> cool down to 55 C at 0.02C/sec -> 55 C 16h
    • Should have added RiboLock after reached 55C since it would be denatured at 95C
  • Ampligase: add 3ul AmpLigase enzyme mix (0.5U/ul AmpLigase in 1X AmpLigase buffer)
  • SplintR: add 3ul SplintR enzyme mix (10ul SplintR + 2ul 10X SplintR Buffer + 4ul Ribolock + 4ul H2O)
  • Ampligase: -> 55 C 20h -> 94C 2min -> add 2ul Exo I/III mix -> 37C 1h -> 94C 2min -> 4C hold
  • SplintR: -> 37 C 30min -> 94C 10min -> add 2ul Exo I/III mix -> 37C 1h -> 94C 2 min -> 4C hold
  • Take 30ul and purify with Zymo columns
    • Left in 4C 1 hour after first column spin down
    • Elute 10ul
