a Structure of polphylipoprotein (PLP). b Phase-contrast images of RGK1 immediately after and 30 min after irradiation with light of 655 nm for 1 min. After 30 min, blebs were formed, and the cells became necrotic. c Overlap image of bright-field and fluorescence images of a PLP-administered RGK1 sample. The fluorescent images are pseudocolored in red. d Series of z-stack fluorescence images of a phagosome after PLP administration (left) and three-dimensional (3D) image formed using the z-stack images (right). The structure of phagolysosome, the binding structure between phagosome and lysosome, is clearly visible, where the lysosome is indicated by the white arrow.
