DNA minimization protocols allow you to manipulate objects while minimizing the amount of DNA you leave on them. Some protocols focus on never leaving DNA traces on an object in the first place. Other protocols focus on removing DNA traces from an object by chemically destroying DNA molecules.
DNA minimization protocols may involve:
- Purchasing an object in individual plastic packaging so that you don't risk leaving DNA on it until you open the packaging.
- Manipulating an object while wearing a new pair of non-permeable gloves (e.g. dish washing gloves) so that there are no DNA traces on the outside of the gloves that could be transferred to the object.
- Storing an object in a new, non-permeable garbage bag so that DNA from the environment doesn't contaminate the object during storage.
- Destroying DNA molecules with sodium hypochlorite, which is present in adequate concentrations in some brands of bleach.
See “Dna You Say? Burn Everything to Burn Longer: A Guide to Leaving No Traces” for protocol suggestions, and the “DNA” topic.
