Abstract: An immunoadjuvant comprising one kind or two or more kinds of immunostimulating substances carried separately by two or more kinds of different microparticle immunostimulating substance carriers, and comprising at least a combination of (a) an inorganic substance such as microparticle calcium phosphate having a size phagocytizable by cells, and (b) precipitates of a soluble protein and a mucopolysaccharide formed by coacervation as the microparticle immunostimulating substance carriers, which is highly safe and can exhibit potent immunoadjuvant activity.

Abstract: An immunoadjuvant which can efficiently exhibit potent adjuvant activity and avoid conditions undesirable for living bodies, and comprises precipitates formed by coacervation of (a) a soluble protein (provided that a soluble protein contained in tuberculin is excluded), and (b) a mucopolysaccharide, and further comprises (c) a soluble protein contained in tuberculin wherein said (c) is coprecipitated with the precipitates.

Abstract: An immunoadjuvant, having a potent cell-stimulating effect and highly safe for living bodies, which comprises a fragment, wherein said fragment is prepared from a solidified material selected from the group consisting of a tissue and a cell of an animal including a human and an ingredient thereof, and from which fragment a soluble ingredient is removed by washing with an organic solvent and/or hot water, and wherein a soluble ingredient derived from a microorganism is immobilized to said fragment.
