Figure 1. Neuropilin-2 expression on human cancer cells.

A, Flow cytometry analysis of NRP2 expression in human cancer cell lines. B, Immunohistochemical staining of NRP2 in human colon tissues and breast tissues (brown). Formalin-fixed paraffin-embedded tissues were incubated overnight at room temperature with anti-human NRP2 antibody. Representative micrographs were taken at an original magnification x1000; NRP2 is expressed at the membrane of human colon and breast carcinomas while it is not expressed in healthy tissues.
