About Peptide Reconstitution

Formula Used

Solvent Volume (ml) = Peptide Weight (mg) ÷ Desired Concentration (mg/ml)

Definitions

Reconstitution
The process of adding a solvent to a lyophilized (freeze-dried) peptide to create a solution.
Concentration
The amount of peptide dissolved in a specific volume of solvent, typically measured in mg/ml.
Solvent
The liquid used to dissolve the peptide, commonly bacteriostatic water, acetic acid, or sterile water.

Tips for Proper Reconstitution

  • Allow the peptide vial to reach room temperature before reconstitution.
  • Gently inject the solvent against the glass wall of the vial, not directly onto the peptide.
  • Swirl the vial gently until the peptide is completely dissolved. Do not shake vigorously.
  • Store reconstituted peptides according to the manufacturer's recommendations, usually refrigerated.
