Method for stabilizing an aqueous alkaline phosphatase solution

摘要

A method for stabilizing an aqueous solution containing alkaline phosphatase or a derivative thereof. The method includes a step of adding, to an aqueous solution containing alkaline phosphatase or a derivative thereof, a compound having a binding activity which is reversible with respect to alkaline phosphatase. According to this method, alkaline phosphatase in a solution can be stored stably for a long period at high temperatures.
