Double immunostaining of a big islet (a) and a small islet (b) in pancreas for glucagon (red) and insulin (brown). Immunostaining of an isolated big islet (c) and an isolated small islet (d) for glucagon (red). The isolated small islet (d) is devoid of glucagon-positive cells. Scale bars represent 50 μm.
