Abstract:
:A hemagglutinin was isolated from hemocytes of the ascidian, Halocynthia roretzi, by a procedure including extraction and ion-exchange chromatography on CM-cellulose. The molecular weight of the hemagglutinin was estimated to be 120,000 by gel filtration. It was resistant to acid treatment but sensitive to alkali or heat treatment. The hemagglutinating activity was inhibited by heparin, chondroitin sulfate, and lipopolysaccharide (LPS), but not by mono- and disaccharides such as N-acetyl-galactosamine, galactose, and melibiose. The hemagglutinin showed binding ability to heparin and LPS, as demonstrated by heparin-Sepharose chromatography and centrifugation experiments, respectively. It was also found that the hemagglutinin can bind to various bacteria such as Escherichia coli, Bacillus subtilis, Vibrio anguillarum, Pseudomonas perfectomarinus, Achromobacter aquamarinus, and Alteromonas putrefaciens, and can agglutinate all of them.
