[Comparative analysis of lectin interaction with blood serum proteins in man, rodents and ungulates].

Studies have been made on the interaction of proteins of the blood serum of man, guinea pig, rat, donkey and ram with concanavalin A, peas lectin and phytohaemagglutinin II. It was found that reactions of the lectins with serum proteins exhibit strictly specific pattern. On the basis of the data obtained, a discussion is made of evolutionary conformation of serum proteins and distribution of lectin receptors within the structure of their molecules.
