Storage & Handling
Storage Conditions:
- Store at -20°C or below in original sealed vial
- Protect from light and moisture
- Do not freeze-thaw repeatedly once reconstituted
- Recommended shelf life: 24 months when stored properly
General Laboratory Handling:
- Handle using standard laboratory safety practices
- Wear appropriate personal protective equipment (gloves, lab coat, safety glasses)
- Use in well-ventilated area or fume hood
- Avoid inhalation, ingestion, or skin/eye contact
- Wash hands thoroughly after handling
Reconstitution:
Reconstitution methods, diluents, and working concentrations must be determined by qualified researchers
according to their specific experimental protocols and institutional guidelines. Aventris does not provide
reconstitution instructions.
