Abstract
A method is provided for purifying uricase by decreasing the amount of active catalase present. The method involves adjusting the pH of a catalase-containing uricase preparation to a pH in the range of about 11 to 13 to inactivate the catalase and recovering a uricase preparation substantially free of active catalase.
