Not a chemical compound; huSSTR2-HEK293 refers to a genetically engineered cell line derived from HEK293 cells that express the human somatostatin receptor subtype 2 (hSSTR2). This cell line is primarily used in biomedical research and drug development, particularly for studying receptor-ligand interactions, screening potential therapeutics targeting somatostatin pathways, and evaluating the efficacy of radiolabeled peptides in neuroendocrine tumor imaging and treatment. It serves as a functional model system for G-protein-coupled receptor (GPCR) signaling and is instrumental in assays involving calcium flux, cAMP inhibition, and receptor internalization.
