Abstract
The present invention relates to reversed phase high-performance liquid chromatography (HPLC) methods useful for the characterisation of glatiramer acetate or similar polypeptide mixtures. The method described herein can distinguish glatiramer acetate from non-conforming copolymers and may be used to choose batches of glatiramer acetate suitable for pharmaceutical use.
