Haemagglutination activity of lectins from extracts of some Vietnam marine sponges

Abstract

Aqueous extracts from 16 species of Vietnam inarine sponges were examined for hacmagglutination activity using native and enzyme-treated different animal and human erythrocytes. Among these, extracts from 14 species were found to have hacmagglutinination activities toward at least one type of erythrocyte tested meaning that 87.5% of the surveyed marine sponge species possess haemagglutination activity. Strong activity was detected in extracts from marine sponge species Acanthella cavernosa, Axinyssa sp., Cinachyrella sp., 01NT.2.4, 3.5, 3.10, 3.11 and 3.18 with enzyme-treated various animal and human erythrocytes.
