Research Peptide Terminology
Plain-language definitions for common catalog, testing, batch, and laboratory-documentation terms.
- Amino acid
- A molecular building block used to form peptide and protein chains.
- Batch / lot number
- An identifier used to connect a group of produced material with its records and documentation.
- Certificate of analysis
- A document reporting the tests performed on a sample or batch and the resulting data.
- Chromatogram
- A visual output showing detected components as peaks after chromatographic separation.
- Identity testing
- Analysis intended to support whether the expected compound is present.
- In vitro
- Research performed outside a living organism, such as in a controlled laboratory system.
- Lyophilized
- Freeze-dried under controlled conditions to remove water and produce a dry material.
- Peptide bond
- The chemical bond connecting amino acids in a peptide chain.
- Purity
- A method-dependent description of the primary detected component relative to other detected components.
- Reconstitution
- Preparing a solution from a dry material using an appropriate solvent and laboratory protocol.
- Sequence
- The ordered arrangement of amino acids in a peptide.
- Stability
- How well a material maintains defined characteristics under specified conditions over time.
