Anti-adrenoceptor beta 1 antibodies are used for the immunodetection of the protein encoded by the ADRB1 gene. In humans, the canonical protein has a reported length of 477 amino acid residues and a mass of 51.3 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, it is known to be involved with brown fat cell differentiation. Post-translational modifications have been described, including phosphorylation and glycosylation. Other names for this target antigen include B1AR, BETA1AR, FNSS2, RHR, beta-1 adrenergic receptor, adrenergic, beta-1-, receptor, beta-1 adrenoceptor, and ADRB1R. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 70 citations in the literature describe the use of adrenoceptor beta 1 antibodies in research. ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
