Confocal microscopy imaging of (A) DAPI-stained nucleus in the
blue channel, (B) Rab11, EEA1, CD63, and LAMP-2 are stained with the
corresponding primary and Alexa Fluor 647 conjugate secondary antibody
in the far red channel, respectively, and (C) denotes the uptake of
coumarin-6-labeled LDC-NPs in differentiated THP-1 cells under the
green channel. (D) Merged imaging of all channels with respective
bleached pink and white coloration, signifying the colocalization
of LDC-NPs in early and recycling endosomal and lysosomal compartments,
respectively, at a fixed magnification scale.
