Abstract:
The localization of the 32-kDa galectin (beta-galactoside-binding lectin) of the nematode Caenorhabditis elegans, which is the first lectin to be found in a nematode, was examined immunohistochemically using an anti-lectin antiserum. The lectin was found to be localized most abundantly in the adult cuticle and also in the terminal bulb of the pharynx. However, it was difficult to locate the galectin in larval animals, though immunochemical experiments suggested its presence. These results suggest that one of the fundamental roles of the galectin may be as a component of the durable outer barrier, as in the case of the morphogenesis of chick embryonic skin.
