In the plasma membrane-enriched fraction of female gametes of Ectocarpus siliculosus (Phaeophyceae) four sex-specific glycoproteins (P2–3, P5, P16) exposing N- acetylglucosamine (GlcNAc) residues were detected in vitro. In immunoblots these proteins were labelled with the GlcNAc complementary lectin...
