Reconstitution reference
| BAC water | 5 mg vial | 10 mg vial | Note |
|---|---|---|---|
| 1 mL | 5.0 mg/mL | 10.0 mg/mL | High concentration |
| 2 mL | 2.5 mg/mL | 5.0 mg/mL | Standard |
| 3 mL | 1.67 mg/mL | 3.33 mg/mL | Dilute |
| 5 mL | 1.0 mg/mL | 2.0 mg/mL | Very dilute |
Add bacteriostatic water slowly down the vial wall — do not inject directly onto the lyophilized cake. Swirl gently; do not shake.
Allow the powder to dissolve fully at room temperature before use. Reconstituted solution should be stored at 2–8 °C and used within 30 days.
Concentrations shown are for laboratory calculation reference only.
