Reconstitution
Also known as: reconstitute peptides · mixing peptides · peptide dilution
The process of dissolving a lyophilised (freeze-dried) peptide in a sterile solvent such as bacteriostatic water before study.
Reconstitution is the process of returning a lyophilised (freeze-dried) peptide to liquid form by adding a sterile solvent — almost always bacteriostatic water — so a precise concentration can be measured out for research.
The solvent is drawn into a syringe and directed slowly down the inside wall of the vial, not squirted straight onto the peptide pellet, which can denature it. The vial is then swirled gently, never shaken, until fully clear.
The volume of water chosen sets the concentration: the same peptide amount in less water is more concentrated per unit volume. A reconstitution calculator removes the arithmetic and prevents dosing errors in research.

RELATED TERMS
Bacteriostatic Water
Sterile water containing 0.9% benzyl alcohol, the standard solvent for reconstituting peptides so a multi-use vial stays sterile.
Lyophilised
Freeze-dried. Peptides are supplied as a lyophilised powder/pellet for stability, then reconstituted before study.
Sterile Technique
The practice of avoiding contamination when reconstituting and drawing from vials — wiping stoppers, single-use needles.
Cold Chain
Keeping temperature-sensitive peptides consistently cool from dispatch to storage to preserve integrity.
International Unit (IU)
A measure of biological activity; on a research syringe the "units" scale is a convenient volume marker, not a mass.
Subcutaneous
Into the layer of fat just beneath the skin — the route most peptide research protocols reference.
