Distribution of glycocompounds in human spermatozoa was studied by using fluorescent lectin-conjugates. Con A bound predominantly to acrosomal and posterior head regions whereas RCA I bound to the acrosomal region of intact spermatozoa, stained in suspension. Other lectins used (LCA, WGA, SBA, PNA) stained the the entire sperm surface. In airdried sperm smears binding of both Con A and RCA I were identical with the staining pattern obtained with living cells whereas LCA, WGA, SBA and PNA now bound heavily into acrosomal region. As a similar staining pattern was obtained with permeabilized sperm cells, this staining is apparently due to binding to intracellular structures. The efficiency of Lens culinaris agglutinin affinity chromatography in purification of human sperm glycoproteins was tested after their external radiolabelling with the neuraminidase/galactose oxidase/sodium borohydride method. 22% of applicated radioactivity could be eluted from the column with the specific inhibitory saccharide, and most of the radiolabelled surface glycoproteins of the whole sperm lysate, were also present in the LCA affinity column eluate. LCA affinity chromatography seems thus be an effective method to enrich membrane glycoproteins of human spermatozoa.
