A method for stabilizing a physiologically active substance produced by recombinant DNA technique, which comprises adding an albumin to an aqueous solution or powder containing the physiologically active substance, and a stable aqueous solution or powder which contains the physiologically active substance and an effective amount of an albumin, said physiologically active substance having cytotoxic activity against L-M cells and being capable of inducing hemorrhagic necrosis of transplanted Meth A sarcoma in the BALB'c mouse. The aqueous solution or powder containing the physiologically active substance can be stored for a prolonged period of time without losing its activity, and is stable on freezing, thawing, lyophilization or the like.
