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 PPE (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. Celvaris does not provide reconstitution instructions.
