Alomone Labs is pleased to offer a highly specific antibody directed against an epitope of rat histamine H2 receptor. Anti-Histamine H2 Receptor (HRH2) (extracellular) Antibody (#AHR-002) can be used in western blot, indirect flow cytometry, immunohistochemistry, and immunocytochemistry applications. The antibody recognizes an extracellular epitope and is thus ideal for detecting the receptor in living cells. It has been designed to recognize H2R from rat and mouse samples. It will not recognize human H2R.
