We have examined the existence of lectin activity in saline-extracted fractions of fish roe. Cell agglutination was observed in 13 of 19 fish species (68%), especially in Cypriniformes and Salmoniformes. A rhamnose-binding lectin was isolated from Osmerus eperlanus mordax (Olive rainbow smelt, Osmeridae, Salmoniformes) roe by affinity chromatography and ion-exchange chromatography. This lectin, termed OML, agglutinated rabbit and human ABO blood group erythrocytes and sarcoma 180 murine tumor
