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.
