Electrophoretic-purified human glycophorin A (GPA) was used to produce its derivatives: (1) glycopeptides were separated and purified from GPA by trypsin digestion; (2) preparation of GPA-antibody and GPA glycopeptide-antibody; (3) preparation of deglycosylated GPA (dGPA); (4) incorporating GPA or dGPA into human RBC membrane lipids to form two kinds of liposomes. The products described above were used to test Plasmodium falciparum FCC1/HN merozoites for their ability to invade human erythrocytes. It was found that GPA-liposomes were able to bind with merozoites and dGPA-liposomes had a negative reaction. GPA, GPA glycopeptide, GPA-antibody, GPA glycopeptide-antibody and GPA-liposome all had the effect to hinder the invasion of merozoites into human erythrocyte while dGPA-liposome had no such an effect.
