Peptide Glossary
Common terms used in peptide research, explained in plain English.
- Peptide
- A short chain of amino acids linked by peptide bonds, used as a research compound in laboratory studies.
- Lyophilisation
- Freeze-drying. Peptides are supplied as a lyophilised powder to maximise stability during storage and transport.
- Reconstitution
- The process of dissolving lyophilised peptide powder in a suitable solvent before use.
- Bacteriostatic Water
- Sterile water containing a small amount of preservative, commonly used to reconstitute research peptides.
- COA
- Certificate of Analysis — a document confirming the identity and purity of a specific product batch.
- HPLC
- High-Performance Liquid Chromatography, an analytical technique used to measure peptide purity.
- Mass Spectrometry
- An analytical method that confirms a peptide's molecular weight and identity.
- Purity
- The percentage of the desired peptide in a sample. Our research peptides are supplied at ≥99% purity.
- Half-life
- The time taken for half of a compound to degrade or clear under defined conditions.
- Sequence
- The specific order of amino acids that defines a peptide and its properties.
- Vial
- The sealed glass container in which lyophilised peptide is supplied and later reconstituted.
- Stability Window
- The documented period during which a reconstituted peptide remains viable when stored correctly.
