PiF [Catalog # P031]

■ Chemical structure & Information
PiF (Pancreatic islet Fluorinated probe) is a superior pancreatic beta cell probe over PiY, facilitating the pancreatic tissue preparation from day to hours. PiF could detect not only healthy pancreatic beta cells, but also transplanted islet in the liver. PiF has built in F atom which could be replaced with 18F for PET imaging. PET imaging of pancreatic islet was demonstrated by replacing 19F with 18F of PiF
■ Cell Image
(A) Fluorescent images were acquired after the cell culture of isolated islets. (Left) Merged fluorescent images of PiF (λex = 535 nm, λem = 585 nm, red) and TPα (λex = 370 nm, λem = 475 nm, green). (Middle) Merged confocal images of PiF (red) and anti-insulin (green: pseudocolor). Anti-insulin was imaged under a Cy5 filter. (Right) Merged confocal images of PiF (red) and anti-glucagon (green: pseudocolor). Anti-glucagon was imaged under a Cy5 filter. Hoechst was used for nuclei staining. (B) In vivo PET/CT images of [ 18F]PiF in ICR mice. ICR mice (n = 3) were intravenously dosed with approximately 7.4 MBq of [ 18F]PiF.
