Peptide Stability and Handling Basics

Research peptides are sensitive to temperature, light, and moisture. Sample integrity depends as much on handling discipline as on initial purity.

General handling principles

• Keep lyophilized material sealed and frozen until it is prepared.
• Minimize freeze–thaw cycles; aliquot where appropriate.
• Protect light-sensitive compounds from prolonged exposure.
• Always reference the COA's validated stability window.

These are laboratory integrity practices for maintaining a reference sample. They are not instructions for any application of the material.
