Isolation and properties of three lectins from mistletoe (Viscum album L.).
Three lectins have been isolated from an extract of mistletoe (Viscum album) by affinity chromatography on partially hydrolysed Sepharose and human immunoglobulin- Sepharose. The lectins differ in molecular weight and sugar specificity (lectin I, mol.wt. 11500, D-galactose-specific; lectin II, mol.wt. 60000, both D-galactose- and N-acetyl-D-galactosamine-specific; lectin III, mol. wt. 50000, N-acetyl-D-galactosamine-specific). All three lectins react with human erythrocytes without specificity for the A, B, and O blood groups. In contrast with abrin and ricin the mistletoe lectins cannot be divided into "toxins" and "haemagglutinins".
