Anti-QRFPR/GPR103 (extracellular) Antibody (#AGR-033) is a highly specific antibody directed against an epitope of the rat QRFP receptor. The antibody can be used in western blot analysis. The antibody recognizes an extracellular epitope and can potentially be used for detecting the receptor in living cells. It has been designed to recognize GPCR GPR103 from rat, mouse, and human samples.
