  • Title: Serological characterization of humoral lectin from Heterometrus granulomanus scorpion hemolymph.
    Author: Ahmed H, Anjaneyulu G, Chatterjee BP.
    Journal: Dev Comp Immunol; 1986; 10(3):295-304. PubMed ID: 3770265.
    Abstract:
    A lectin in the hemolymph of Indian scorpion Heterometrus granulomanus was detected by agglutination of human and animal erythrocytes. The agglutinating activity was enhanced in presence of Ca2+ ion. The lectin shows specificity for sialic acid like many other sialic acid-specific lectins such as "Limulin", as the agglutination of erythrocytes was completely abolished by treatment with Vibrio cholerae neuraminidase. However, neuraminidase-treated rat and mouse erythrocytes exhibited high titers. This result was substantiated by crossed-absorption test which suggests the adjunct specificity of the Heterometrus lectin for these cells. Hemagglutination-inhibition results of the lectin indicate that sialic acid including its derivatives and sialoglycoconjugates are the inhibitors among which glycophorin was most potent.
