Analysis Note
Agglutination activity is expressed in μg per 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 erythrocytes after 1 hr incubation at 25 °C.
Biochem/physiol Actions
Psophocarpus tetragonolobus agglutinin is not blood group specific, but has an affinity for N-acetyl-D-galactosamine. Conjugates are prepared from purified lectin.
