If possible unscrew the lower parts of the pipette barrel and wash in soapy water. (b) The dial and top of the pipette where the thumb is placed is a large source of contamination. (c) Treat the washed pipettes and test tube racks with UV light in a biosafety cabinet or in a UV light box for 1 h. (d) Use a gDNA eliminator column twice to ensure gDNA removal
