  • Patent number: 10317376
    Abstract: In one aspect, the disclosure provides methods of distinguishing a glycosaminoglycan from one or more other components in a sample by subjecting the sample to size-exclusion chromatography using a mobile phase having a pH of 6.8 or lower. A mobile phase having a pH of 6.8 or lower is found to improve the separation of glycosaminoglycans from proteins during size exclusion chromatography. In some embodiments, improved separation is due to the low pH of the mobile phase causing elution of less dispersed fractions of the protein and/or glycosaminoglycan. In some embodiments, the overlap between protein and/or glycosaminoglycan fractions is reduced.
