Cellular uptake of antibody conjugated and unconjugated nanoparticles in various cell lines.
Notes: (A) Cellular uptake of DOX-NP and DOX-Ab-NP in SKBR-3, MCF-7, and MDA-MB-231 cells observed by confocal microscopy at 1 and 6 hrs, respectively. (B) Cellular uptake of antibody-conjugated blank nanoparticles in SKBR-3, MCF-7, and MDA-MB-231 cells observed by confocal microscopy at 6 hrs.
Abbreviations: DOX, doxorubicin; Ab, antibody; NP, nanoparticle.
