Laboratory Handling
- 1mg vial + 2 mL solvent = 0.5 mg/mL
- Store lyophilized powder sealed at −20 °C, protected from light and moisture; allow the vial to reach room temperature before opening to limit condensation.
- Reconstitute with sterile or bacteriostatic water, adding solvent slowly down the vial wall and swirling gently — do not shake.
- Store reconstituted solution at 2–8 °C and use within about 28 days; avoid repeated freeze–thaw cycles by aliquoting if longer storage is needed.
- Record lot number and reconstitution date on every vial so results trace back to the matching Certificate of Analysis.
