Biochem/physiol Actions
HAA has anti-A human blood group specificity and an affinity for terminal N-acetyl-α-D-galactosaminyl residues. Conjugates are prepared from affinity purified lectin.
Preparation Note
Affinity purified by a modification of the method of Hammarstrom and Kabat.
Analysis Note
Where reported, agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, of a 1 mg per mL solution. This activity is the lowest concentration to agglutinate a 2% suspension of human blood group A erythrocytes after 1 hour incubation at 25 °C.
