MSDS for Lenti viral vectors
Lentiviruses are members of the family Retroviridae. They are enveloped viruses with a singlestranded linear RNA genome. Lentiviruses vector systems can include human viruses (e.g., human immunodeficiency virus). They can also include viruses of animal origin (e.g., feline
immunodeficiency virus, equine infectious anemia virus, simian immunodeficiency virus).
-
PATHOGENICITY
Lentiviruses can cause severe immunologic and neurologic disease in their natural hosts. The clinical manifestations of infection include non-specific symptoms such as lymphadenopathy, anorexia, chronic diarrhea, weight loss, fever and fatigue.
-
MODE OF TRANSMISSION
Lentiviruses are transmitted by direct contact with non-intact skin and mucosa and by parenteral inoculation. The hazard of aerosol exposure is unknown.
-
LABORATORY CONTAINMENT REQUIREMENTS
Containment level 2 or 2+ in some cases.
-
ANIMAL RESEARCH FACILITY CONTAINMENT REQUIREMENTS
- Recombinant lentiviral vector inoculation : containment level 2.
- Housing of animals infected with replication defective recombinant lentiviral vector :
containment level 2 for 7 days. After this period, animals can be transferred to
containment level 1. - Housing of animals permissive for recombinant lentiviral vector replication : containment
level 2 for duration of experiment.
-
DISINFECTANTS
0.5% sodium hypochlorite (1/10 dilution of bleach), 70% ethanol, 2% glutaraldehyde and 4% formaldehyde.
-
PHYSICAL INACTIVATION
Autoclave : 121°C, 30 minutes, 15 psi.
