Abstract
The antigenic cross-reactivity between purified chick, eel and mouse electrolectins (endogenous β-D-galactoside specifc lectins) have been studied using a solid phase radioimmunoassay. The immune serum raised against the eel electrolectin crossreacts both with the chick and the mouse electrolectins, while the anti-chick electrolectin anti-serum recognizes only the eel but not the mouse electrolectin. These findings are analyzed in terms of the phylogenetic distance separating the species considered; they suggest that electrolectins fulfil a fundamental biological function
