About Glucagon
The protein encoded by this gene is actually a preproprotein that is cleaved into four distinct mature peptides. One of these, glucagon, is a pancreatic hormone that counteracts the glucose-lowering action of insulin by stimulating glycogenolysis and gluconeogenesis. Glucagon is a ligand for a specific G-protein linked receptor whose signalling pathway controls cell proliferation. Two of the other peptides are secreted from gut endocrine cells and promote nutrient absorption through distinct mechanisms. Finally, the fourth peptide is similar to glicentin, an active enteroglucagon. [provided by RefSeq, Jul 2008]

About DyLight 650
DyLight™ 650 is a red-emitting fluorophore that excited by the 640 nm laser and collected using a 670/30 nm bandpass filter. DyLight™ 650 has an excitation peak at 652 nm and an emission peak at 672 nm, and is spectrally similar to Alexa Fluor™ 647 and Cy5. DyLight™ 650 is most commonly used in flow cytometery and fluorescence microscopy applications.
