Anti-GCG Antibody

Sourced from Antibodies.com, this affinity-purified rabbit polyclonal reagent is raised against glucagon (GCG) and is supplied as a 50 µl aliquot at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol — a cryoprotective buffer that allows convenient storage at −20 °C while avoiding repeated freeze/thaw cycles. The antibody is unconjugated, has an estimated purity of greater than 95%, and is validated for Western blot (WB) and immunohistochemistry (IHC) applications. It has been tested for reactivity against human, mouse and rat samples, making it a broadly useful tool for researchers studying proglucagon processing, pancreatic islet biology, intestinal L-cell signalling and metabolic regulation. Because the host species is rabbit and the preparation is polyclonal, the reagent recognises multiple epitopes across the GCG protein, which generally yields stronger signals in IHC and more tolerant performance across denaturing conditions in WB. The product is intended for research use only and is well suited to experiments where total endogenous GCG needs to be detected in tissue lysates or fixed sections. For best results, aliquot upon first thaw and keep the glycerol-containing formulation at −20 °C to preserve activity over the lifetime of the vial.
