Target Capture - Troubleshoot v6 probes (Part II)

Background

1) v6 probes, all-in-one KLN mastermix with old Epicentre dNTP     rxn's 1,5
2) v6 probes, all-in-one KLN mastermix with new NEB dNTP           rxn's 2,6
3) v6 probes, separate KLN mastermix with old Epicentre dNTP       rxn's 3,7
4) v6 probes, separate KLN mastermix with new NEB dNTP             rxn's 4,8

Procedure

  • Prep two different dNTP dilutions:
    • Epicentre MDA dNTP = 1/25d
    • NEB dNTP = 1/10d

Rxn's 1,5 (all-in-one KLN, old Epicentre dNTP), 2ul added

  • Thermocycler (continued): Add 2ul or 4ul KLN to each rxn -> Incubate 60C 4hr -> 94C 2min -> add 2ul ExoI/ExoIII mix (1:1) to each rxn -> 37C 2hr -> 94C 5min -> Hold 10C
    • Note: Right before 4hr is up, prep the ExoI/ExoIII mix at 1:1 ratio
    • Note: Made sure to equilibrate to 37C for at least 1min before adding in Exo
