Patent 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.
