Anti-GRPR Antibody

Raised in rabbit and affinity-purified as a polyclonal reagent, this unconjugated primary antibody targets the Gastrin-Releasing Peptide Receptor (GRPR), a G protein-coupled receptor studied in neurobiology, gastrointestinal physiology, and oncology research where it has been linked to proliferation and migration in lung, breast, prostate, and pancreatic cancer models. Distributed by Antibodies.com, the reagent supports laboratories investigating bombesin-like peptide signalling.

In western blot and immunohistochemistry workflows, the antibody detects the receptor in human, mouse, and rat samples, enabling cross-species expression profiling. Each vial is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a cryoprotectant, shipped in a 100 µl volume suited to routine blotting and staining experiments.

The glycerol-containing buffer protects the antibody during freeze-thaw handling, and the formulation works with both chromogenic and fluorescence-based detection in fixed tissue sections and prepared lysates. Researchers characterising neuropeptide receptor distribution, GPCR signalling cascades, or tumor biomarker profiles apply this reagent to localise GRPR in normal and diseased tissues.
