🧪 PEPTIDE CALCULATOR
Correct Peptide Reconstitution
Our peptides are delivered in the form of lyophilized, i.e. freeze-dried powders, which are resistant to short-term temperature fluctuations during transport. At room temperature, peptides in powder form remain stable even for several weeks. But it is essential to store them properly to maintain their integrity.
Before usage for research purposes, the lyophilized powder must be reconstituted by mixing it with an appropriate solvent to form a solution. Accurate reconstitution is vital to ensure that the peptides retain their potency and bioactivity for further research and trials.
Peptide Reconstitution Protocol

As with all research work, for successful peptide reconstitution absolute sterility and purity are required when preparing the conditions.
- ✓ Thoroughly wash your hands and don sterile protective clinical gloves and goggles
- ✓ Ensure your workspace is impeccably clean
- ✓ Have all necessary tools ready:
- Lyophilized peptide in a glass vial
- Sterile syringe
- Solvent (Bacteriostatic water)
- Gloves and safety glasses
Cleanliness and sterility of the environment is very important for accurate research results.
The process of peptide reconstitution requires careful selection of the solvent based on the specific properties of the peptide. At Particle Peptides, we recommend and provide bacteriostatic water for this purpose.
- Temperature equilibrium: Before reconstituting the peptide, ensure that the peptide powder and solvent that were stored in the cold are brought to room temperature. Using the solutions while they are still cold may interfere with the reconstitution process.
- Vial preparation: Carefully remove the central part of the metal cap from the vial and disinfect the upper surface with an alcohol swab. This step is crucial for maintaining sterility and preparing the vial for the reconstitution procedure.
- Clean solvent vial: Repeat the same cleaning process for the solvent vial.
Precise handling is crucial when adding solvent to the lyophilized peptide.
Using a sterile syringe, carefully withdraw the required amount of solvent and slowly inject it into the peptide vial.
Pro tip: Tilt the vial at a 45° angle to allow the solvent to gently run down the interior wall.
This method helps minimize the formation of bubbles and foam, ensuring a smooth and even dissolution of the peptide.
Proper storage of lyophilized peptide powder is crucial for maintaining its stability.
Powder Storage
Store the peptide powder at a minimum of +4°C for short-term use, and ideally at -20°C or lower for long-term storage.
Solution Storage
Peptide solutions, once reconstituted, have a limited shelf life. To extend their viability, consider freezing aliquots of the solution.
⚠️ Avoid repeated cycles of freezing and thawing, as these can compromise peptide integrity.
