Laboratory handling
Reconstitution guide
A repeatable bench process for dissolving lyophilized peptides into a clear, stable stock solution.
- 01
Prepare the bench
Let the sealed vial and diluent reach room temperature. Wipe both rubber stoppers with a fresh alcohol swab.
- 02
Measure the diluent
Using a sterile graduated syringe or pipette, measure the exact volume you entered in the calculator.
- 03
Add and dissolve
Release the diluent slowly down the inside wall of the vial, not onto the powder. Swirl gently until dissolved. Do not shake.
- 04
Label and store
Label the vial with the concentration and date. Store refrigerated at 2 to 8 °C (36 to 46 °F), protected from light.
- Keep unopened lyophilized vials frozen until use.
- Swirl, never shake. Foaming degrades peptides.
- Keep solutions away from direct light and heat.
