From: The Duffy binding protein (PkDBPαII) of Plasmodium knowlesi from Peninsular Malaysia and Malaysian Borneo show different binding activity level to human erythrocytes

Fig. 2

Binding activity level of PkDBPαII to human and macaque erythrocytes. Number of rosettes formed by COS-7 cells transfected with PkDBPαII of Peninsular Malaysia and Malaysian Borneo. A positive rosette was defined as more than half the surface of the transfected cells covered with attached erythrocytes, and the total number of transfected COS-7 cells counted for each independent experiment was 1500 per experiment. Data are shown as the mean rosettes number of three independent experiments. The error bar represents ±standard deviation. Statistical difference between PkDBPαII of Peninsular Malaysia and Malaysian Borneo, and between human and macaque erythrocytes is indicated with double asterisk (P < 0.001)
