Instead of plasmid or genomic DNA, you can use a colony from the agar plate as template DNA. You should use a sterile toothpick, pick into the colony and spread it in the PCR tube.

For a 10 µl reaction (Taq Polymerase Peqlab):

  • 1 µl Buffer S
  • 0,2 µl dNTP's (10 mM)
  • 0,2 µl Primer fw
  • 0,2 µl Primer rev
  • 0,04 µl Taq Polymerase
  • 8,36 µl Water

PCR Program

  • 95°C 5 min

35 times the following cycle

    • 95°C 1 min
    • 55°C 30 sek. (°C depends on your primers)
    • 72°C 1 min/kb

cycle end

  • 72°C 10 min
  • 10°C hold
