Epidermal growth factor receptor-targeted immune magnetic liposomes capture circulating colorectal tumor cells efficiently

Figure 3 Size of the captured circulating tumor cells and color of stained magnetic beads. A: Localization and distribution of EILs in HT-29 cells. Cells were cultured in FITC-labeled EILs-containing medium on bottom of a glass dish (35 mm dish with 14 mm bottom wells) for 30 min followed by treatment with DAPI dye and Dil dye for 5-10 min, separately, and subsequent examination by confocal microscopy; B: Prussian blue staining of EGFR IMLs with HT-29 Cells. (Scale bar: 5 μm). IMLs: Immune magnetic liposomes; EILs: EGFR-targeted immune magnetic liposomes.
