Lyophilized powder containing phosphate buffer salts and NaCl

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.
