      • 1st attempt: template DNA was used directly; concentration too high (failure)?
      • 2nd attempt: 100X, 1000X dilutions attempted without success; this time, over-dilution or stringent annealing temp (68°C) may have been culprit?
      • 3rd attempt: 10X dilutions, annealing temp lowered to 65°C -> success!
