  1. The p120, p96 and p68 forms of PfA-M1 as compared to Plasmepsin I (PlasI), SERP and Aldolase were quantified in the six fractions of the FV isolation procedure. Fractions are as described on Figure 7A, i.e. fractions A and B corresponding to soluble proteins, fraction C to membranes, vacuoles, debris and fraction E to pure FV. Bands intensities were obtained by scanning each column of the Western Blot on Figure 7B. Values are expressed as a % of the sum of intensities in the six fractions for a given protein.
