摘要:
An aspect of the present invention relates to stable formulations of chondroitinase and to methods of purifying chondroitinase. The methods of purifying chondroitinase includes the steps of extracting the enzyme from a cell, separating the chondroitinase from the crude cell extract using cation-exchange chromatography, removing impurities through gel filtration chromatography, and removing endotoxin through an anion-exchange membrane to produce a purified chondroitinase.
