Abstract

Concanavalin A (Con A), a lectin isolated from jack beans, binds specifically to saccharides with terminal α--mannopyranosyl, α--glucopyranosyl or β--fructofuranosyl residues (Goldstein, Hollerman & Merrick, 1965; Goldstein, Hollerman & Smith, 1965; Goldstein & So, 1965). Glycoproteins, present in human serum (Leon, 1967; Morse, 1968) or representing structural components of membranes of mammalian cells (Inbar & Sachs, 1969) or of enveloped viruses (Oram 1971; Becht, Rott & Klenk, 1972; Calafat & Hageman, 1972; Klenk, Rott & Becht, 1972) react with Con A. Recently, Cawley (1972) observed that Con A partially precipitated hepatitis B antigen. Results presented here extend this finding and show that the interaction between hepatitis B antigen and Con A may be utilized as a step in purifying the distinct morphological forms of this antigen.

Four vol. of serum containing hepatitis B antigen were mixed with increasing amounts (0.2 to 1.0 vol.) of a solution of Con A (1 g in 26.4 ml of saturated NaCl; Miles-Yeda Limited, Rehovoth, Israel).
