Reconstitution Basics

Add water slowly

Run bacteriostatic water down the inside wall of the vial. Never inject the stream directly onto the lyophilised powder.

Swirl, don't shake

Rotate the vial gently until fully dissolved. Agitation can denature the peptide chain.

Store cold

Reconstituted vials belong at 2–8°C and are typically stable for up to 30 days. Unopened lyophilised vials store best frozen.

More water, easier measuring

Adding 2 mL instead of 1 mL doubles the draw volume, which makes small measurements far more accurate.
