Abolition of IgM-binding capacity and CSA-binding capacity of parasites of P. falciparum line SD2O2CSA upon incubation with increasing concentrations of trypsin protease. Data from a representative experiment are shown. Binding to negative control (BSA) spots was less than 5 iRBC per 10 high-power fields. Two further experiments gave consistent results.
