    • Abstract


      Saline extracts of several varieties ofTriticale had haemagglutinin activity against rabbit, rat and fowl erythrocytes. In contrast to the wheat germ lectin theTriticale lectin was inactive against human B, 0 blood group type erythrocytes and rather high concentrations of the lectin are needed to agglutinate human A blood group type erythrocytes. TheTriticale lectin was purified about 20-fold with a 10% recovery of activity from one of the varieties (DTS 138) by (NH4)2SO4 fractionation followed sequentially by chromatography on DEAE-cellulose and sulphopropyl-Sephadex. Approximately 4 μg of the purified lectin caused visible agglutination with trypsinised rabbit erythrocytes. Among a variety of sugars tested D-glucose, D-mannose and N-acetyl-D-glucosamine (2·5-7·5mM) caused inhibition of agglutination.
