Biochem/physiol Actions
PA-I has a major affinity for
Packaging
Package size based on protein content. Vial content based on protein by biuret.
Physical form
Lyophilized powder containing approx. 80% protein (biuret), balance primarily sodium citrate, plus traces of calcium chloride, magnesium chloride and manganese chloride
Preparation Note
Purified by affinity chromatography using a modification of Gilboa-Garber.1
Analysis Note
Agglutination activity is expressed in μg/ml and is determined from serial dilutions of a 1 mg/ml solution using phosphate buffered saline, pH 7.0. This activity is the lowest concentration to agglutinate a 2% suspension of neuraminidase treated human blood group A erythrocytes after one hr incubation at 25 °C.
Highly purified.
