A document from a quality testing laboratory that confirms a peptide batch meets specified purity, identity, and quality standards.
A Certificate of Analysis (COA) is an official quality document issued by an analytical testing laboratory that certifies a specific batch of peptide meets predetermined specifications for identity, purity, potency, sterility, and other parameters. A comprehensive COA typically includes HPLC purity data, mass spectrometry molecular weight confirmation, amino acid analysis, endotoxin levels, sterility testing results, and batch-specific lot numbers. Third-party COAs from independent laboratories are considered more reliable than in-house testing, as they eliminate potential conflicts of interest. ORYN provides batch-specific COAs for every product, verified by independent third-party laboratories, with purity consistently exceeding 99%. Researchers should always request and review a COA before using any peptide in experimental protocols.
High-Performance Liquid Chromatography, the gold-standard analytical method for determining peptide purity by separating and quantifying components in a liquid sample.
An analytical technique that measures the mass-to-charge ratio of ions to identify and quantify molecules, essential for verifying peptide identity and purity.
Analytical procedures that determine the percentage of desired peptide in a sample versus impurities, contaminants, or degradation products.
Independent laboratory verification of peptide quality by an external organisation with no financial interest in the product, ensuring unbiased results.
A laboratory technique for separating mixture components based on differential interactions with a stationary and mobile phase, used extensively in peptide analysis.
A quality control assay that detects bacterial lipopolysaccharide contamination in injectable peptide products to ensure safety.
