Abstract

PURPOSE: To prepare a uricase membrane having excellent dimensional stability, mechanical strength, and storage stability, with little deactivation of uricase, by casting an acidic solution of chitosan and uricase, and immersing the dried film thus prepared in an alkaline solution.
CONSTITUTION: Uricase is dissolved in an acidic aqueous solution of chitosan having a concentration of about 0.5W2% and a pH value of about 1W6, and cast to a horizontal plate to obtain a membrane having a thickness of about 10W100μ. The membrane is dried to a water-content of ≤ about 15%, and coagulated by immersing in an alkaline solution having a pH of 9W13 for about 10W60 minutes.
