Recombinant DNA (rDNA) or Synthetic Nucleic Acid Molecule use in Animals

Housing containment guidelines:

Four protocols have been developed by the Office of Animal Resources (OAR) and Environmental Health & Safety (EHS) for use of recombinant or synthetic nucleic acid molecules in animals. The Institutional Biosafety Committee (IBC) determines which animal biosafety level must be used, primarily based on the agents used in an approved rDNA Registration Document (rDNARD). Special protocols have been developed for Animal Biosafety Level 1 (ABSL1), Animal Biosafety Level 2a (ABSL2a) and Animal Biosafety Level 2c (ABSL2c) for small animals or Animal Biosafety Level 2n (ABSL2n) for large animals.  Animal Biosafety Level 3 (ABSL3) is described within the Biosafety Level 3 Core Facility manuals.

For questions regarding the above protocols, contact OAR staff at 335-7985.

For questions related to your approved rDNARD, contact EHS’s Biosafety staff at 335-8501.

Disposal practices

Whether or not recombinant or synthetic nucleic acid molecules have been administered to an animal, most carcasses/tissues are double-bagged in plastic biohazard bags and staged for disposal by placing the bag(s) in “biohazard” labeled containers located within the walk-in coolers, refrigerators, or freezers of each animal facility.  Exceptions to this policy are outlined below:

  • Drosophila species

    • Euthanize followed by autoclaving and disposal in “biohazard” labeled containers or regular trash OR
    • Euthanize followed by disposal in “biohazard” labeled containers.
       
  • Caenorhabditis elegans

    • Dispose in “biohazard” labeled containers
       
  • Danio rerio

    • Eggs, Fry and Adults
      • Euthanize followed by autoclaving and disposal in “biohazard” labeled containers or regular trash, OR
      • Euthanize followed by disposal in “biohazard” labeled containers.
         
  • Xenopus species

    • Eggs, Tadpoles and Adults
      • Euthanize followed by autoclaving and disposal in “biohazard” labeled containers or regular trash, OR
      • Euthanize followed by disposal in “biohazard” labeled containers.

All animals, in which recombinant or synthetic nucleic acid molecules have been administered, must be properly treated/decontaminated prior to final disposal.  Stericycle will properly treat and dispose of animal carcasses and tissues which are placed into the “biohazard” labeled containers located in the animal facilities.  Any animal disposed of in the laboratory (Drosophila, C. elegans, D. rerio, or Xenopus) must be properly treated before disposal, regardless of the assigned animal biosafety level (ABSL1 or ABSL2).
