Purification process of the PirABvp toxin from ECPs of Vibrio parahaemolyticus in rat stroma.

Fraction Total Protein (mg) HAU a Specific Activity b
ECP 195.4 160.0 0.82
Unretained fraction 194.42 0.0 0.0
Retained fraction (PirABvp) 0.980 160.0 163.26

a HAU = hemagglutinating activity units tested in presence of rat erythrocytes. b Specific activity = HAU/mg protein.
