Elimination of Tumor Cells Using Folate Receptor Targeting by Antibody-Conjugated, Gold-Coated Magnetite Nanoparticles in a Murine Breast Cancer Model
Figure 1
FR expression by 4T1 cells. (a) 4T1 cells were labeled with anti-FR antibody. Left panels show differential interference contrast (DIC) images; right panels show the fluorescence image of the same field. Negative control cells were labeled with the secondary antibody alone. Images were taken at 600x magnification. (b) Cells were labeled as above and analyzed by flow cytometry. Marker indicates positive staining for FR.
