Abstract
Though 3',5′-cyclic diadenylic acid was conventionally provided only as a freeze-dried product, a solid material other than a freeze-dried product and a manufacturing method thereof is provided. By a step of adding acid to an aqueous solution of 3′,5′-cyclic diadenylic acid so as to lower pH to 1 to 3, an inclusion compound of 3′,5′-cyclic diadenylic acid can be obtained. Said manufacturing method is an extremely simple and easy method and does not need a special machine or the like.
