Reconstitution & storage.
General laboratory handling reference for lyophilized peptides. Always follow your institution's protocols.
Equilibrate
Let the sealed vial reach room temperature before opening to prevent condensation.
Add solvent
Slowly add bacteriostatic water down the vial wall — never directly onto the powder.
Dissolve gently
Swirl, don't shake. Let it go fully clear; avoid foaming or vortexing.
Store cold
Refrigerate the reconstituted solution at 2–8°C; minimize freeze-thaw cycles.
Concentration (mg/mL) = vial mass (mg) ÷ solvent added (mL). Use this to plan your working dilutions for in-vitro research.
10 mg ÷ 5 mL = 2 mg/mL
Risk stays with us, not you.
