Abstract
Methods for analyzing, selecting, characterizing or classifying compositions of a co-polymer, e.g., glatiramer acetate are described. The methods entail analysis of pyro-glutamate in the composition, and, in some methods, comparing the amount of pyro-glutamate present in a composition to a reference standard. In some cases, the methods entail treating the co-polymer with pyro-glutamate aminopeptidase to cleave N-terminal pyro-glutamate residues.
