Overview
Anti-Somatostatin Receptor Type 2 (extracellular) Antibody is an antibody targeting SSTR2, SS2R, Smstr2, SRIF1A Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IFC, IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: SSTR2, SS2R, Smstr2, SRIF1A (also reported as SSTR2, SS2R, Smstr2, SRIF1A).
- Immunogen/epitope region: Extracellular, N-terminus.
- Homology note: Mouse - identical; human- 12/14 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Cited use: IHC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Somatostatin is a small cyclic peptide that is widely expressed throughout the central nervous system and peripheral tissues.1 In peripheral tissues, somatostatin exerts inhibitory effects on secretion processes, whereas in the brain, it acts as a neurotransmitter in both a stimulatory and an inhibitory manner.1,2Somatostatin mediates its action via six high affinity G-protein coupled receptors (SSTR1, SSTR2a, SSTR2b, SSTR3, SSTR4, and SSTR5), which are encoded by five genes.1,2 Expression of the different receptors is developmentally regulated in a time- and tissue-specific manner.2Somatostatin receptors have been found on a variety of neuroendocrine tumors, such as paragangliomas, carcinoids, and breast tumors.3 Synthetic peptide derivatives of somatostatin have been successfully used in the treatment of neuroendocrine malignancies and in vivo imaging of tumors that are positive for somatostatin receptors.4In general, SSTR2 is the most common SSTR subtype found in human tumors, followed by SSTR1, with SSTR3 and SSTR4 being less common.
Research relevance and current trends
- Comparing target expression across perturbations, genotypes, or treatment conditions.
- Interpreting localization shifts alongside pathway or phenotypic readouts.
- Using orthogonal controls (KO/KD, peptide competition, isotype concepts) to support conclusions.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-SR006.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
