Amplification from FS_22 to FS_13(s); 2.7 kb

lane5=log2 Marker, lane6=68touchdown (FS13_short), lane7=68touchdown (FS13), lane8=72 2-step (FS13_short), lane9=72 2-step (FS13); run at 100 V, 0.8 % gel (TAE)

4 reactions (with long and short primer FS13 and with conditionI and conditionII)

Results:

  • Amplification of DelOP failed again
  • PCR will be repeated, annealing will be carried out 65°C (touchdown) as primer binding seems not to occure at high temperatues as the ones tested in the last amplification attempts

  • Band were cut out and DNA purified using QIAquick Gel Extraction Kit to verify amplicon in a re-PCR
