Anti-GCG Antibody

From Antibodies.com, this rabbit polyclonal antibody binds glucagon (GCG), the 29-residue peptide hormone secreted by pancreatic alpha cells that opposes insulin in blood glucose regulation. The unconjugated reagent is validated for Western blot and immunohistochemistry across human, mouse, and rat samples, supporting work on islet biology, diabetes models, and metabolic tissue profiling. Supplied as 100 µl at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol as a cryoprotectant, the stock should be refrigerated and aliquoted on first use to limit freeze-thaw cycles of the antibody. Polyclonal recognition of multiple sites along the glucagon sequence helps detection of the proglucagon precursor and mature hormone in pancreatic lysates and fixed tissue sections.
