STABILIZER FOR AQUEOUS SOLUTION OF PHYSIOLOGICALLY ACTIVE SUBSTANCE AND AQUEOUS SOLUTION OF PHYSIOLOGICALLY ACTIVE SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To provide a stabilizer for an aqueous solution of a physiologically active substance, which suppresses deactivation of a physiologically active substance in an aqueous solution, stabilizes an aqueous solution of a physiologically active substance for a long period of time, does not cause a nonspecific reaction even in use in a diagnostic etc., and provides sufficient sensitivity.;SOLUTION: The stabilizer prevents deterioration of a physiologically active substance in preservation of an aqueous solution of a physiologically active substance composed of a physiologically active substance and water and comprises an arginine ester having a modified amino group at the α-position and/or its salt and a cationic polymer (A).;COPYRIGHT: (C)2010,JPO&INPIT
