Figure 3From: Screening and selection of peptides specific for esophageal cancer cells from a phage display peptide library Immunofluorescen labeled phage clones binding Eca109 cells and normal human esophageal epithelial cells (magnification, 400×). Two clones, P4 and P12, were evaluated for their binding to Eca109 cells (A, D), to normal esophageal epithelial cells (B, E), and to controls (e.g., cells not incubated with anti-M13 antibody) (C, F), respectively.Back to article page
