In vitro binding of [18F]exendin-4 in rat pancreas. a Clear tracer binding was observed after incubating pancreatic tissue sections with [18F]exendin-4 (2.5 nM) b co-localization with the islets was observed by staining the same sections with insulin antibody. c–d Islet labeling was not observed, when an excess of cold exendin-3 was added. Scale bar 1000 μm
