| Analysis Note | Agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, of a 1mg/ml solution. This activity is the lowest concentration to agglutinate a 2% suspension of human blood group O erythrocytes after 1 hr incubation at 25 °C. |
| Biochem/physiol Actions | ABA is a mixture of two phytohemagglutinins with similar specificities for carbohydrate receptors.1 The lectin is not blood group specific, but has an affinity for fetuin. |
| Preparation Note | Purified by affinity chromatography. |
| Physical form | Lyophilized powder containing NaCl |
