Peptide Reconstitution Guide
How to prepare, reconstitute, and store your peptide ?
Properly prepare, reconstitute, and store your lyophilized peptides to ensure their stability, purity, and reliable research results.
Preparation best practices
Accurate concentration
Optimal storage
Understanding peptide reconstitution
Our peptides are supplied in lyophilized form (sterile dehydrated powder) to preserve their stability during transport and storage.
Before use in research, this powder must be reconstituted with a suitable solvent to obtain a solution at the desired concentration.
Stability
Lyophilization ensures optimal peptide stability before reconstitution.
Reconstitution
Adding a suitable diluent yields a homogeneous, ready-to-use solution.
Accurate concentration
Correct dilution ensures an exact concentration for reliable sampling.
Storage
Appropriate storage conditions preserve the quality and stability of the peptide.
Reconstitution steps
Prepare the environment
Work in a clean, disinfected environment. Wash your hands and wear clean gloves. Ensure you have all the necessary materials within reach.
- Lyophilized peptide vial
- Sterile syringe
- Solvent (bacteriostatic water recommended)
- Alcohol wipes
Prepare the vial and the solvent
Remove the peptide and the solvent from the refrigerator and allow them to reach room temperature. Clean the rubber stoppers of both vials with an alcohol wipe.
Draw up the solvent
Using a sterile syringe, draw up the exact volume of solvent required for reconstitution. Refer to our dosage calculator or the product sheet for the recommended volume.
Add the solvent
Gently insert the needle along the wall of the vial and tilt it at a 45° angle. Slowly inject the solvent so that it flows gently down the inner wall. Avoid injecting directly onto the powder to reduce foaming.
Dissolve the peptide
Gently swirl the vial between your fingers until completely dissolved. Do not shake vigorously: this may damage the peptide structure. The resulting solution should be clear and free of visible particles.
Important tip
Always use sterile equipment and avoid any contact between the needle and the powder to preserve peptide purity. Dispose of the syringe after each use.
Storage of peptide solutions
Once reconstituted, peptide solutions have a limited shelf life. Proper storage conditions are essential to maintain their stability and integrity.
Refrigerator (+2°C to +8°C)
In general, reconstituted peptide solutions remain stable for 3 weeks or more. Store them in the coldest part of the refrigerator.
Freezer (-20°C or below)
A still lyophilized (not reconstituted) peptide vial can be stored in the freezer for long-term storage.
Important
Never place a vial back in the freezer once the peptide has been reconstituted . The freezer is reserved for the lyophilized vial, before reconstitution. A prepared solution must only be stored in the refrigerator — freeze/thaw cycles of a reconstituted solution compromise peptide integrity and stability.
Calculate your exact dosage
Once your peptide is reconstituted, use our calculator to precisely determine the volume to draw based on your syringe and the desired dose.
