WebMar 23, 2024 · Here, we compare new and well-established methods, including traditional amino acid analysis (AAA), aromatic amino acid analysis (AAAA) based on the amino acids phenylalanine and tyrosine, reversed-phase liquid chromatography of intact proteins with UV absorbance measurements at 220 and 280 nm (LC-220, LC-280), and … WebPurpose: To develop a rapid 2D HPLC method capable of fully characterizing a biologic formulation containing a mixture of a protein and a carbohydrate. Methods: The biologic sample was first analyzed using reverse phase HPLC and UV at 280 nm to measure a surrogate protein bioformulation, bovine serum albumin (BSA) with a carbohydrate.
