Product information
Oxytocin is a synthetic cyclic nonapeptide composed of nine amino acid residues in the sequence Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH₂ (CYIQNCPLG-NH₂), featuring an intramolecular disulfide bridge between the two cysteine residues and a C-terminal primary amide. It is structurally classified within the neurohypophyseal nonapeptide family and is closely related to vasopressin, from which it differs by two amino acid residues. This product is supplied as a lyophilized powder containing 5 mg net peptide per vial, synthesized by solid-phase peptide synthesis (SPPS) and characterized by HPLC-UV (purity) and LC-MS (identity). It is intended exclusively for in-vitro laboratory research and analytical applications. In the research literature, oxytocin is referenced in the context of the oxytocin receptor (OXTR), a class A (rhodopsin-type) G-protein-coupled receptor, and is frequently used as a reference peptide in receptor-binding, structure-activity, and peptide-stability investigations.
