Amino Acid, Peptide & Protein Standards
Amino acid, peptide, and protein reference materials are crucial to different analyses, including proteomics and food testing. We offer specially designed standards and certified reference materials of various heavy and light peptides, enzymes, intact proteins, amino acids, and stable isotope‑labeled analogs. Our reference materials are compatible with mass spectrometry testing applications in biomarker discovery, pharmaceutical research, clinical and diagnostic testing, top-down and bottom-up proteomics, and food authentication.

- Flyer: Stable Isotope Labeled Amino Acid Mixes
Amino acids play a central role in biochemistry. They are the building blocks of proteins and precursors to the biosynthesis of various secondary metabolites. From being used as food additives (as artificial sweeteners and flavor enhancers) to the synthesis of drugs, biodegradable plastics, and chiral catalysts— amino acids have a wide range of uses.
- Flyer: Food Allergen Protein Standards
We are proud to introduce a new comprehensive range of purified food allergen protein standards manufactured by Indoor Biotechnologies. Indoor Biotechnologies’ allergens are purified by affinity chromatography and/or HPLC. Protein identity and amino acid composition are verified by InBio® using MS (mass spectrometry) and amino acid analysis. Immune reactivity is validated by monoclonal antibody binding.
Amino Acids
Our amino acids portfolio includes neat TraceCERT® certified reference materials (CRMs). Our CRMs are certified by quantitative nuclear magnetic resonance (qNMR) following ISO/IEC 17025 and ISO 17034 guidelines. We also offer certified reference material solutions and analytical standards of amino acid mixes.
Peptides
Our range of peptide standards includes HPLC-compatible analytical standards and MS PhosphoMix phosphopeptide standards. Phosphopeptide standards are used to test strengths and weaknesses of phosphopeptide samples by mass spectrometric analysis. They contain synthetic phosphopeptides with their sequence derived from naturally occurring peptides. MS PhosphoMix standards are available in three types; each has the same amino acid sequence but different phosphorylation sites. All the MS PhosphoMix standards are available in their naturally occurring isotopic abundance (light) version or the stable isotope enriched (heavy) version.
Proteins
We offer an extensive range of protein reference materials. As part of this, our fully intact, Cerilliant® protein certified reference materials are used as reference standards in qualitative and quantitative LC-MS/MS applications for diagnostic testing, pharmaceutical release testing, and food safety testing. The portfolio also includes monoclonal antibodies from USP and NIST for biopharmaceutical method development and system suitability. We offer more than 50 reference materials for food allergen proteins including standards from InBio™ and certified reference materials from Cerilliant. Also, from InBio we offer a set of SARS-CoV-2 related proteins. In addition, we offer protein standards for size exclusion chromatography.
