CATALYST FOR SUGAR CHAIN CLEAVAGE

摘要

A catalyst capable of specific cleavage of one or two or more sugar chains selected from the group consisting of hyaluronic acid, chondroitin sulfate A, chondroitin sulfate C and chondroitin sulfate D. There are further provided an agent capable of specific cleavage of the sugar chains; a medical drug characterized by being used in specific cleavage of the sugar chain present in anatomy; a method of specifically cleaving the sugar chains; a process for specifically producing the sugar chains whose molecular weight has been reduced; and processes for producing the above catalyst, cleavage agent and medical drug.
