Reconstituting & Storage
Research peptides are supplied as a lyophilised (freeze-dried) powder and must be reconstituted with a suitable solvent before use in the laboratory. Follow the steps below to mix and store your compounds correctly and preserve their integrity.
Prepare your workspace
Work on a clean, disinfected surface. Wipe the rubber stopper of both the peptide vial and the bacteriostatic water vial with an alcohol swab and allow them to dry.
Draw your solvent
Using a sterile syringe, draw the required volume of bacteriostatic water. The chosen volume determines the concentration of your final solution.
Add solvent slowly
Insert the needle at an angle and let the water run gently down the inside wall of the peptide vial. Never inject directly onto the powder — it can damage the peptide.
Let it dissolve
Swirl the vial gently and let it sit. Do not shake. The powder should dissolve into a clear solution within a few minutes.
Store correctly
Reconstituted peptides should be refrigerated at 2–8°C and used within the documented stability window. Lyophilised (powder) vials can be kept frozen for long-term storage.
A note on concentration
The amount of bacteriostatic water you add sets the concentration of the final solution. A larger volume of solvent yields a more dilute solution; a smaller volume yields a more concentrated one. Always document your dilution so measurements remain consistent throughout your study.
