Fig. 4From: Biodistribution of arctigenin-loaded nanoparticles designed for multimodal imagingTarget localization using BF NPs and AF NPs. A General strategy for fluorescent labeling of the target protein. BEAS-2B cells were treated with AF or BF NPs, followed by the DAPI fluorescent marker. Fluorescence and DIC images are shown. All scale bars 20 μm. B The histogram of flow cytometry analysis is shown in a. The scatter diagram of flow cytometry analysis is shown in b Back to article page
