Subcellular localization by Confocal microscopy: (a) MDA-MB-231 cells: differential interference contrast (first column), FITC fluorescence confocal channel (second column) and overlay of both channels (third column) images for bis-MTX-ASO-FITC incubated with either 1DHFR2RGD4C (upper panel) or 13DHFR2RGD4C (lower panel) at 37 °C. (b) FITC fluorescence channel for 1DHFR2RGD4C nanostructures (first column), cholera toxin Alexa Fluor 594 (second column), overlay of green and red channel (third column).
