Binding of Homing Peptides to LNCaP Prostate Cancer Cells

(A) LN1, LN2, and LN3 peptides modified with a biotin molecule were incubated with LNCaP cells for 24 h at a concentration of 1 μg/μL and the binding affinities of the respective peptides were compared using fluorescence with Avidin D-conjugated TRITC (biotinylated peptides are stained red). Scale bars, 100 μm. (B) The percentage of TRITC-positive LNCaP cells bound with prostate cancer homing peptides (n = 6 per group). (C) Comparison of fluorescence intensity of each target peptide bound to LNCaP cells (n = 6 per group). Error bars, SD. **p < 0.01.
