Abstract
Proteinaceous bioactive substances (including lymphokine and peptide hormone) in dry solid are extremely stabilized by the presence of the specific polysaccharide mainly composed of repeating maltotriose units. Pullulan, elsinan, and their partial hydrolysates are feasible as the polysaccharide. The weight ratio of the polysaccharide to the substance which effectively stabilizes the latter substance is at least 0.5 on the basis of dry solids. The dry solid is advantageously usable as a test reagent, injection, granule, tablet, suppository or ointment.
