Abstract
A chromatographic process for the copurification of chondroitinase proteins useful in ocular surgery for non-surgical disruption of chondroitin sulfate, the molecule which mediates the attachment between the retina and vitreous body in the human eye. The process involves the use of ion exchange resins in conjunction with an affinity elution with chondroitin sulfate to afford copurification of the proteins.
