Abstract:This study investigated the immune-enhancing effects of polysaccharides extracted from Gloiopeltis furcata (red seaweed) with different molecular weights. A crude polysaccharide mixture was hydrolyzed using acid treatment (0.1 N HCl) and three molecular weight fractions were generated and filtered using centrifugation: (≤10 kDa, 10 to 100 kDa, and 100 kDa. Nitric oxide (NO) production in RAW264.7 cells treated with 0.01-0.5 μg/mL polysaccharides ≥100 kDa was 12.28-19.05 μM. Treatment with polysaccharides ≥100 … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
