METHOD FOR STABILIZING USEFUL PROTEINS AND USEFUL PROTEIN COMPOSITIONS

摘要

A method for stabilizing useful proteins characterized by mixing the useful proteins with aqueous solutions of compounds having a fundamental structure of arabic acid; and stabilized useful protein compositions wherein the useful proteins contain compounds having a fundamental structure of arabic acid. It is preferable to use acacia as the compounds having a fundamental structure of arabic acid, while the useful proteins are typified by cytokines. This method is particularly efficacious in stabilizing interferons. Also, processes for producing and stabilizing canine interferon- gamma are disclosed in detail. <IMAGE>
