Abstract
The present invention relates to simple size exclusion chromatography (SEC) analytical methods useful for the assessment of accurate molecular weight distributions (MWDs) of certain polypeptide mixtures known as glatiramoids. The use of a SEC method based on one or more broad MWD standards furnishes the absolute (not relative) molecular weight distribution profile of complex polypeptide mixtures like, for instance, the glatiramer acetate (GA) polymer.
