Charles River also provides amino acid analysis and extinction coefficient determination for client products. We have performed these studies on a wide range of biological molecules, including peptides, complex and PEGylated biologics, molecules containing unusual amino acids, monoclonal antibodies, vaccines, gene therapy vectors, and heavily glycosylated glycoproteins.
