Oxytocin is a cyclic nonapeptide research peptide composed of the sequence Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, commonly represented as CYIQNCPLG-NH2. It is studied in laboratory models involving oxytocin receptor signaling, neuroendocrine pathway regulation, calcium mobilization, GPCR signaling, and peptide-receptor interaction systems.
Oxytocin is primarily investigated through its interaction with the oxytocin receptor, also known as OXTR, a G protein-coupled receptor expressed across central and peripheral research models. Published research has evaluated OXTR-associated signaling through Gq/11, Gi/o, PLC, IP3, calcium, PKC, MAPK, CaMK, and CREB-related pathway systems.
This product is supplied as a 10mg lyophilized research peptide vial. It is intended strictly for qualified laboratory research use only and is not for human use, veterinary use, diagnostic use, therapeutic use, cosmetic use, or consumer health applications.

Mechanism Overview
Oxytocin Research Peptide is provided as a laboratory research material for studies involving oxytocin receptor biology, GPCR signaling, calcium pathway activation, and neuroendocrine signaling models.
OXTR / GPCR Signaling
Oxytocin is studied through its interaction with the oxytocin receptor, OXTR. OXTR is a 7-transmembrane G protein-coupled receptor that has been reported to couple with Gq and Gi proteins, with downstream signaling involving PLC, PKC, MAPK, CaMK, and CREB-related transcriptional pathways.
Calcium & PLC Pathway Research
In OXTR-associated models, oxytocin receptor activation is commonly studied in relation to phospholipase C signaling, IP3 generation, intracellular calcium mobilization, and downstream calcium-sensitive signaling pathways. These pathways are relevant to smooth muscle, neuroendocrine, and cell-signaling research systems.
Neuroendocrine & Behavioral Pathway Models
Oxytocin signaling is widely studied in central and peripheral research models involving neuroendocrine communication, social-behavior pathway mapping, reproductive signaling models, stress-associated circuitry, and peptide receptor regulation. These research areas should be framed as pathway models only, not as product benefits or intended uses.
These mechanisms are derived from biochemical, cell-based, preclinical, and review-based research on oxytocin and the oxytocin receptor system. Functional outcomes may vary depending on receptor expression, model system, peptide handling, exposure conditions, and assay design.
All lots are manufactured under internal quality control standards. Identity and purity are verified prior to release to support consistency across laboratory research workflows.
