We are looking for a antibody which is really specific for the angiotensin II AT1 receptor . We have used the antibody SC1173 from Santa Cruz and were always puzzled by the results until we found the publication of Julius Benicky et al. (Cell Mol Neurobiol. 2012 Nov;32(8):1353-65.), describing that several commercial antibodies (among these antibodies both from Santa Cruz) against the receptor are unspecific. Any recommendation of a good antibody?
