ABSTRACT:
A water soluble immunopotentiating agent is derived from yeast cell wall material, including mechanically disrupted yeast cell walls, proteolyzed yeast cell wall material and carbohydrate-protein complexes found in yeast cell wall material, through extraction with a water-phenol mixture. The water soluble agent is isolated from the water phase and can be further purified, as through dialysis, to remover low molecular weight components.
