FIGURE 16.16 | Immunohistochemical

Preparation of Mammalian Pancreatic Islet

With immunohistochemical preparation, different cell types are visible in the
pancreatic islet. This high-magnification image shows precise distribution of the

two major cell types in the pancreatic islet. The glucagon-producing cells (A
cells) are stained bright red and are located peripherally in the islet. The insulin-
producing cells (B cells) are stained bright green and are located on the inside
of the islet surrounded by the peripheral A cells.
