Table 1: Quantitative summary of F. gigantica ESPs purification. aProtein was measured as described by Lowry et al. [22]. bA unit of activity defined as the amount of protein required to give one well of agglutination. cSpecific activity which is the number of activity per µg of protein and is related to the starting crude ESPs.
