Storage & handling

  • Store lyophilised vials refrigerated at 2–8 °C, protected from light and moisture.
  • Do not freeze lyophilised material unless the batch record states otherwise.
  • Keep vials upright in the original carton until reconstitution.
Reconstituted
  • After reconstitution with bacteriostatic water, refrigerate at 2–8 °C.
  • Typical research use window: within 28 days when using BAC water (batch-dependent).
  • Discard if the solution becomes cloudy, discoloured, or particulate.
Handling
  • Use aseptic technique; wipe the stopper with an alcohol swab before each draw.
  • Do not shake vigorously — swirl gently to dissolve.
  • For laboratory research use only. Not for human or veterinary use.
