Definitions of the terms used on Peptra Labs labels, batch records and purity reports
The vocabulary on a peptide label, a Certificate of Analysis and a purity report
Research peptides are described in a compact technical shorthand. A vial label carries a batch number, a Certificate of Analysis reports purity by HPLC and identity by mass spectrometry, and the material itself arrives lyophilised and has to be reconstituted before use. Each entry below defines one of those terms in plain language, with no efficacy or health claims attached.
Every definition is written for laboratory buyers deciding what to check before ordering. Where a term relates to batch documentation, the corresponding records are published in the lab reports archive, and the longer explanation of how to read one is in the Certificate of Analysis guide.
All Peptra Labs material is supplied for in-vitro laboratory research by qualified professionals. Research use only: not for human or veterinary consumption.
9 terms
- Batch / Lot Number
- The batch number is the identifier that links a physical vial to a specific production run and to its analytical records.
- Certificate of Analysis (COA)
- Lot-specific document that records available purity and quality testing information for a peptide batch.
- HPLC purity
- The percentage of a peptide sample that consists of the target compound, measured by high-performance liquid chromatography.
- Lyophilised (freeze-dried)
- A drying technique used to preserve peptides in a stable solid form by removing water under low pressure and temperature.
- Mass spectrometry (MS)
- Analytical technique used to evaluate peptide molecular mass when that test is available for a batch.
- Peptide
- A short chain of amino acids linked by peptide bonds, smaller than a protein and central to many biochemical research applications.
- Peptide storage
- Recommended conditions for keeping peptides stable in the laboratory.
- Reconstitution
- The process of dissolving a lyophilised peptide back into an aqueous solution for laboratory use.
- Research Use Only (RUO)
- Regulatory designation indicating a product is intended exclusively for laboratory or non-clinical research, not for human or veterinary use.
