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.
