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.
Claims11
The process for the preparation of a water soluble immunopotentiating agent from components of yeast cell walls which comprises subjecting yeast cell wall material, proteolyzed yeast cell wall material or a carbohydrate-protein yeast cell wall material to extraction with water and phenol and thereafter isolating the water soluble agent.
