Title: METHOD FOR STORING AQUEOUS SOLUTION CONTAINING LEUCO-TYPE CHROMOGEN
Abstract:
Provided are: a method for storing an aqueous solution containing a leuco-type chromogen, which enables the stable storage of the leuco-type chromogen in the aqueous solution; a method for stabilizing a leuco-type chromogen; and a liquid reagent containing a leuco-type chromogen. An aqueous solution containing a leuco-type chromogen can be stored stably by adding at least one component selected from the group consisting of a phenazine-type compound and a phenoxazine-type compound to the aqueous solution containing the leuco-type chromogen. A leuco-type chromogen can be stabilized by allowing the leuco-type chromogen to co-exist in an aqueous solution containing at least one component selected from the group consisting of a phenazine-type compound and a phenoxazine-type compound.
