Markers to identify goblet cells.

Identification of goblet cells in porcine small intestine and colon are shown. Goblet cells, the mucus producing cells, were identified by immunostaining for MUC2, a component of mucin, and UEA-1, a lectin that specifically binds to alpha-linked fructose receptors. The mucinous secretions of multiple cells in both the small intestine and colon were positively identified. All specific markers (red). Nuclei (blue). Scale bar 200 µm, inset scale bar 50 µm.
