Amino Acid, Peptides & Protein Standards

Designed to accommodate top-down and bottom-up proteomic workflows, our amino acids, peptides, and protein analytical standards include heavy and light peptides, enzymes, intact proteins, and amino acids as well as their stable-isotope labeled analogs. These standards are suitable for mass spectrometry-based or immunoassay testing applications in biomarker discovery, pharmaceutical research, clinical and diagnostic testing, proteomics, and food authentication.
