[Cys2, Tyr3, Orn5, Pen7-amide]-Somatostatin 14 (7-14)

[Cys2, Tyr3, Orn5, Pen7-amide]-Somatostatin 14 (7-14) is a synthetic research peptide in the somatostatin family. The listed sequence/design is D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2. Somatostatin peptides and analogs are research ligands for SSTR1-SSTR5. Sequence modification and cyclization have been used extensively to define receptor subtype selectivity and binding.

Because this product may be a fragment, substituted analog, stereochemical variant, or terminally modified form, its activity should not be assumed to be identical to the native parent peptide. Peptide solubility, aggregation, adsorption to surfaces, and stability can vary with sequence, concentration, pH, ionic strength, and terminal modifications, so assay-specific reconstitution and storage conditions should be validated experimentally.
