Scientific reference — frequently asked questions.
Plain-language answers about research peptides, purity standards, and laboratory handling. For research use only.
Research peptides are short chains of amino acids synthesized for use in controlled laboratory environments. They are studied for their interaction with specific biological pathways and are intended exclusively for in-vitro or preclinical research, not for human consumption.
High-Performance Liquid Chromatography (HPLC) is the analytical method used to separate, identify, and quantify each component in a peptide sample. A purity value above 99% indicates that the target sequence accounts for more than 99% of the material, with any residual content tightly controlled.
Lyophilization — also known as freeze-drying — is a dehydration process that removes water from a frozen peptide under low pressure. The result is a stable, dry powder that preserves molecular integrity during storage and transport and is reconstituted in a sterile solvent before use.
Lyophilized peptides should be stored at 2–8°C, protected from light and humidity. Reconstituted material is typically refrigerated under controlled conditions and used within the stability window described in its protocol documentation.
Reconstitution water is a sterile water solution used in laboratory environments as a diluent for reconstituting lyophilized peptides. It typically contains a small amount of preservative — most commonly 0.9% benzyl alcohol, giving it bacteriostatic properties — to inhibit microbial growth in multi-use protocols.
All PROGENYX compounds are intended exclusively for in-vitro and preclinical research conducted by qualified personnel. They are not approved for human consumption, clinical treatment, or diagnostic use, and must be handled according to applicable laboratory regulations.
Handling should follow standard laboratory practices: appropriate personal protective equipment, controlled environmental conditions, traceable documentation, and proper sharps and biological-waste disposal. Each batch is released with a certificate of analysis that documents identity, purity and storage conditions.
