ACIDIC BACTERIAL EXOPOLYSACCHARIDE HAVING IMMUNOPOTENTIATING ACTIVITY
Document Type and Number:
WIPO Patent Application WO/2024/071336
Kind Code:
A1
Abstract:
The present invention relates to a bacterial exopolysaccharide having a repeating structure comprising a series of repeating units represented by formula (I), and to the use of the bacterial exopolysaccharide for immunopotentiation. (In formula (I), n represents an integer of 0 or 1, independently for each repeating unit.)
