Figure 7From: Fabrication and characterization of DNA-loaded zein nanospheresConfocal images of HEK 293T cells with associated fluorescent 80:1 spheres (A, 600X magnification, 0.1 μg DNA/well) and 250:1 spheres (C, 600X, 0.1 μg DNA/well), and Caco-2 cells with associated 80:1 spheres (B, 600X, 0.1 μg DNA/well) and 250:1 spheres (D, 600X, 0.1 μg DNA/well). It should be noted that not all of the particles fluoresced in the images as some were out of the focal plane of the microscope. Scale bars represent 20 μm.Back to article page
