Characterization of PNPs@M-Ep167-193. A. Transmission electron microscopy (TEM) image of PNPs@M-Ep167-193. The scale is 200 nm. B. SDS–PAGE analysis. The macrophage membrane (MM) protein (20 μg) was resolved by 12% SDS–PAGE. C. Surface charge determination. The results are shown as the mean ± SE. D. DLS determination of the hydrodynamic diameters. The results are shown as the mean ± SE
