Packaging
Package size based on protein content
Physical form
Lyophilized powder containing Tris succinate, NaCl and calcium acetate
Preparation Note
Purified by affinity chromatography.
Analysis Note
Agglutination activity is expressed in μg per mL and is determined from serial dilutions in phosphate buffered saline, pH 7.4, containing 0.1 mM CaCl2, of a 1 mg per mL solution. This activity is the lowest concentration to agglutinate a 2% suspension of human blood group B erythrocytes. Bacterial agglutination is determined from serial dilutions of a 1 mg/ml solution in 0.01 M Tris, 0.15 M NaCl, pH 7.4, 0.01M CaCl2 with 1 mg/ml albumin and 0.92% TWEEN®.
