As with all research work, for successful peptide reconstitution absolute sterility and purity are required when preparing the conditions. Begin by thoroughly washing your hands and donning sterile protective clinical gloves and goggles. Ensure that your workspace is impeccably clean, and that you have all the necessary tools:

• 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.

Before reconstituting the peptide, ensure that the peptide powder and solvent that were stored in the cold are brought to the room temperature. Using the solutions while they are still cold may interfere with the reconstitution process.

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. 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. 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. 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. Peptide solutions, once reconstituted, have a limited shelf life. To extend their viability, consider freezing aliquots of the solution.

In general, peptide solutions remain stable for 3 or more weeks at +4°C and 3-4 months at -20°C. Avoid repeated cycles of freezing and thawing, as these can compromise peptide integrity.
