Anti-SSTR1 antibodies are used in the immunodetection of the protein somatostatin receptor 1. In humans, the canonical protein has a reported length of 391 amino acid residues and a mass of 42.7 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in many tissues, such as the duodenum and small intestine. A member of the G-protein coupled receptor 1 protein family, SSTR1 is a known receptor for somatostatin with higher affinity for somatostatin-14 than -28. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include SS-1-R, SS1-R, SS1R, SST1, somatostatin receptor type 1, and SRIF-2. SSTR1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SSTR1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
