P. falciparum invasion inhibition assay performed over two life cycles. Mean parasitemia obtained from two repeated assays (each performed in duplicate) with different concentrations of OPN (ranging from 200 ng/mL to 12 800 ng/mL) added to FCR3S1.2 parasites. There was no statistically significant difference between the mean parasitemias when OPN was added in the different concentrations. PBS and heparin (100 µg/mL) were added as controls
