Agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, of a 1 mg/ml solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes after 1 hr incubation at 25 °C.
PSA is not blood group specific, but has an affinity for terminal α-
Conjugates are prepared from affinity purified lectin.
Purified by affinity chromatography.
