SCREENING AND PRELIMINARY CHARACTERIZATION OF HEMAGGLUTININS IN SOUTHERN VIETNAMESE MARINE ALGAE

Tóm tắt

Forty-two species of marine algae belonging to Chlorophyta, Rhodophyta and Phaeophyta from the Ninh Thuan coast were examined for hemagglutinations activity with native and enzyme –treated different animal and human erythrocytes. All extracts agglutinated at least one type of erythrocytes tested. The strongest activities were found in the rabbit and horse erythrocytes by two Chlorophyta (Caulerpa sertularioidesf. longipes, Halimeda discoidea) and one Rhodophyta (Gelidiella acerosa). There was only one species (Halimeda discoidea) which has agglutinated with all the erythrocytes tested. The hemagglutinin-inhibition assays performed with monosaccharides and glycoproteins indicated that none of the hemagglutinins had affinity for monosaccharides but they were inhibited by some glycoprotein tested.
