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.

Analysis of amino acid copolymer compositions

An animal waste collection device is able to illuminate the area where a pet has left fecal matter at night by a battery operated lighting system build into the device. The device consists of two separate lighting systems, one operated by either of two momentary switches located in the handle of the device located on the right end and the left end of the handle. When either button is depressed the general area where the pet has left the fecal matter is illuminated by two LED lights, one of each side of the device. The operator will pull the operating handle upward to open the two opposing jaws of the device. On the opening of the jaws, two additional LED lights will illuminate, activated by a micro switch sensing the opening of the waste collection jaws over the fecal matter being collected. On collection of the fecal matter into the hopper of the device, the operator releases the activation handle and the two LED lights illuminating the hopper area turn off. The device also contains reflective tape on each side of the device so that when the operator is walking their pet at night, there is a potential for someone seeing the reflective tape and realize that there is a person walking their pet.

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.
