Amino Acids

Certified Amino Acid Reference Standards for Nutritional Testing, Metabolomics, and Biopharmaceutical Characterization 

Clinivex provides amino acid reference standards characterized for use in quantitative amino acid analysis (AAA), metabolic disorder screening, peptide mapping, and biopharmaceutical raw material testing – spanning essential, branched-chain, aromatic, and sulfur-containing amino acids alongside clinically significant non-standard forms including hydroxyproline, citrulline, and homocysteine. Each standard is confirmed for chemical identity, chiral purity, and assigned concentration by NMR and LC-MS, supporting USP, EP, and AOAC method-aligned workflows in food safety, inherited metabolic disease diagnostics, and protein therapeutic characterization. Our amino acid reference standards deliver the analytical precision and regulatory traceability your laboratory quality programs demand.

Clinivex supplies every standard with a traceable Certificate of Analysis (CoA) documenting purity, structural confirmation, and moisture content aligned with ISO 17025 and cGMP quality expectations. Sourced from accredited manufacturers with established compendial supplier qualifications, our materials integrate reliably into your method validation and routine QC workflows. For molecular biology and genomics applications requiring nucleic acid analytical standards, our nucleic acid reference standards portfolio covers DNA and RNA standards for PCR validation, NGS calibration, and qPCR quantification across clinical and research laboratories.
