SSTR2 (Somatostatin receptor 2) is a novel multi-domain protein belonging to a family of cytoskeletal anchoring proteins. It consists of six N-terminal ankyrin repeats followed by SH3 and PDZ domains, several proline-rich regions, and a C-terminal sterile α region.

Anti-SSTR2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

SSTR2 (Somatostatin receptor 2) is a regulatory peptide widely distributed in tissues. It is involved in several cellular functions including, neuroendocrine and exocrine secretions, and proliferation. In neuronal tissues, it interacts with the inhibitory G-proteins in both the chambers, presynaptic and postsynaptic, to control the synaptic responses. It has the ability to control the proliferation of both normal and neoplastic cells. It is abundantly present at the plasma membrane of several tumorous cells such as pancreatic, gastrointestinal, breast carcinoma, neuroblastomas etc. Thus, SSTR2 has been proved as a potential prognostic marker for certain malignancies.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
