Reconstitution
For peptides supplied as lyophilised powder, reconstitute in bacteriostatic water or sterile saline at the concentration appropriate to your protocol. Allow the vial to come to room temperature before opening, add solvent slowly down the inside wall (do not directly onto the powder), and gently invert until clear. Do not vortex.
Reconstituted solutions are typically stable at 2–8°C for the durations published in the corresponding peer-reviewed reference. For long-term storage, aliquot and freeze at −20°C; avoid repeated freeze–thaw cycles.
