Reconstitution
Dissolving a lyophilised peptide in an appropriate aqueous vehicle prior to research use.
For laboratory and research use only — not for human consumption.
Reconstitution converts a lyophilised peptide from a stable dry powder back into solution. The standard vehicle for injectable research preparations is bacteriostatic water (water containing 0.9% benzyl alcohol). Sterile water for injection is used where bacteriostatic preservatives are unwanted. Reconstitution volume is calculated from desired working concentration; the vial is brought to room temperature first, the vehicle is added against the glass wall (not directly onto the peptide cake), and the vial is gently swirled — not shaken — until dissolved. Reconstituted peptides are typically refrigerated and used within days to weeks, or frozen in single-use aliquots at -80 °C.
