Before you start

  1. Dilute Wash Solution B concentrate 5-fold with ethanol 96% (add 4 volumes of ethanol 96% to the concentrate volume labeled on the bottle), label the cap with a mark that ethanol has been added.
  2. Add 1 mL of Proteinase K Dissolution Buffer in a tube with lyophilized Proteinase K, carefully mix, discard drops by centrifugation.
    ! Prepared proteinase K solution should be stored in a freezing chamber at −20 °C.
  3. If Lysate Solution BB or Wash Solution MAG A contains a precipitate, warm them up in a thermostat up to 50 °C and wait until completely dissolved.
  4. If using a plate shaker, choose optimal conditions for efficient mixing:
    • Make sure that the plate is tightly fixed in the shaker.
    • Add 1 mL of water to plate wells and cover the plate with foil. Determine the maximal shaker rate with which water from the wells does not splash out from the well to the foil.

Preparation of samples

Epithelium swabs:

  1. Add 1 mL of PBS in a clean 1.5 mL tube.
  2. Carefully wash the stick with the epithelium swab with PBS. Cut off the upper part of the stick and close the tube.
  3. Shake the contents of the tube using vortex for 2–3 min.
  4. Use 200 µL of the supernatant as a sample.

Whole blood: Carefully mix blood in the tube and use 200 µL as a sample.
