Fig. 3From: The Duffy binding protein (PkDBPαII) of Plasmodium knowlesi from Peninsular Malaysia and Malaysian Borneo show different binding activity level to human erythrocytesBinding inhibition of PkDBPαII to erythrocytes by anti-Fy6 treatment. a–d PkDBPαII incubated with 1% human erythrocytes; e–h PkDBPαII incubated with 1% macaque erythrocytes; a, b, e, f COS-7 cells transfected with PkDBPαII of Peninsular Malaysia; c, d, g, h COS-7 cells transfected with PkDBPαII of Malaysian Borneo; a, c, e, g erythrocytes not treated with anti-Fy6; b, d, f, h erythrocytes treated with anti-Fy6. Rosettes (red arrows) observed under inverted light microscope at ×200 magnification. No rosettes seen in b and d. Rosettes are more saturated on macaque erythrocytesBack to article page
