Human stomach antrum and G cell immunochemistry for gastrin and PHA-L. (A) Gastrin, phytohemagglutinin-leucoagglutinin (PHA-L, marker of complex type carbohydrate residues which are expressed in gastric parietal cells), and nuclei (blue) in the antrum of fresh human stomach. Scale bar = 10 μm. (B) Gastrin and PHA-L staining in G cells isolated from human stomach and gastrin staining in SW626 cells (ovarian adenocarcinoma cells). G cell- and SW626 cell-control using non-specific rabbit IgG antibody show almost no staining. NG = negative control, non-specific rabbit IgG antibody. Scale bar = 10 μm.
