Size

10 μg/vial, 50 μg/vial, 1 mg/vial

Handling and Storage

Reconstitution

It is recommended to redissolve in sterile deionized water.

Shipping

The product is shipped with blue ice.

Storage & Stability

36 months at -20°C to -80°C in lyophilized state

6 months at -20°C to -80°C under sterile conditions after reconstitution

7-10 days at 2°C to 8°C under sterile conditions after reconstitution.

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
