The molecular weight and theoretical pI values of the identified proteins were calculated according to the Compute pI/Mw tool from the SIB Bioinformatics Resource Portal (http://web.expasy.org/compute_pi/). The results of visual quantification of the protein concentrations found in highly pathogenic compared to weakly pathogenic trophozoites are indicated in the last column (Regulation).
