Reconstitution returns the lyophilizate to a liquid state. The procedure respects both the fragility of the molecule and the sterility of the preparation.
Bring to room temperature
Let the lyophilized vial reach room temperature before opening it, to prevent condensation from introducing moisture.
Add the diluent along the wall
Inject the diluent by letting it run slowly down the inner wall of the vial, never as a direct stream onto the powder cake; the mechanical impact can degrade the molecule.
Dissolve by gentle swirling
Swirl the vial gently, without shaking. Vigorous shaking creates foam and can denature the peptide. The solution should be clear.
Refrigerate and label
Store refrigerated and label with the compound, concentration and reconstitution date.
Aseptic technique —disinfecting the stopper, not touching sterile surfaces, using clean materials— is non-negotiable: the preservative in bacteriostatic water limits, but does not eliminate, the risk of contamination.
