cynoSSTR2-HEK293 is a genetically engineered cell line used primarily in drug discovery and pharmacological research. It serves as a functional assay system for studying somatostatin receptor 2 (SSTR2) activity, particularly in the development of radiolabeled tracers and targeted therapies for neuroendocrine tumors. Due to its stable expression of the SSTR2 receptor, this cell line is widely used in binding assays, signal transduction studies, and high-throughput screening of potential therapeutic compounds. It is also instrumental in evaluating the efficacy and specificity of SSTR2-targeting drugs, including peptide receptor radionuclide therapy (PRRT) agents. Its consistent response makes it a reliable tool for preclinical testing in oncology and endocrinology research.
