The hemolymph agglutinin of the freshwater crab Travancoriana charu recognized with high avidity the simple sugar galactose and the amino sugar N-acetyl glucosamine. The sialoglycoprotein BSM was the strongest glycoprotein inhibitor. Hemagglutination activity (HA) was characterized using several kinds of mammalian erythrocytes and the highest hemagglutination titer was observed against dog erythrocytes containing NeuGc / NeuAc. Maximum hemagglutination of the calcium dependent hemagglutinin was observed at pH 7.5 and temperature 30ᵒC. The agglutinin was sensitive to di- / tetra sodium EDTA and trisodium citrate. Protease treatment enhanced the hemagglutinability. However, treatment with sialidase and denaturing agents caused a decline in the HA titer. Further, cross adsorption studies suggested the presence of a single agglutinin in the hemolymph.
