Table 1: Purification chart of Zizyphus oenoplia seed lectin (ZOSL). Haemagglutination assays were conducted with a suspension of rabbit erythrocytes. It was observed that as the degree of purification increases, the haemagglutination activity also increases. (Haemagglutination assays were conducted with a suspension of rabbit erythrocytes. a) HAU- Hemagglutination Unit, b) SA- Specific activity, ASP fraction- Ammonium sulphate precipitated fraction, ACF fraction- Affinity chromatography fraction, IEC fraction- Ion-exchange chromatography fraction).
