Immunohistochemical analysis of IL-17, IL-22, and IL-23 in human colon biopsies.

<p>Immunohistochemical staining of (<b>A</b>) IL-17, (<b>B</b>) IL-22, and (<b>C</b>) IL-23 in colon biopsies from patients with colorectal cancer. Paraffined sections of human colon biopsies were obtained from patients with colorectal cancer (<b>b</b>), and non-cancerous tissue (<b>a</b>). Human IL-17, IL-22, and IL-23, were detected using anti-human monoclonal antibodies from Santa Cruz. Staining with mouse IgG1 isotype was used as the negative control. Stained tumor cells are shown at a final magnification of ×400.</p>
