Oxytocin is an artificially synthesized cyclic nine-amino-acid polypeptide with intramolecular disulfide bond structure, produced via mature solid-phase peptide synthesis and multi-step reverse-phase chromatographic purification technology. It features fixed complete cyclic amino acid sequence, stable three-dimensional molecular spatial conformation and consistent batch-to-batch component proportion.
This neuroendocrine cyclic polypeptide acts as a core standardized experimental material widely applied in neurobiology, cell biology and molecular endocrinology research fields. It is extensively adopted by university life science laboratories, biotechnology R&D centers and global academic research groups. Under strictly controlled sterile laboratory environments, researchers utilize Oxytocin to carry out systematic basic research including cyclic peptide structural characteristic identification, binding affinity analysis between polypeptide ligands and cell surface target receptors, intracellular multi-stage biochemical cascade reaction rules and neuroendocrine-related signal cross-talk network exploration.
Full-process closed-loop quality monitoring and batch full sampling inspection are implemented throughout the whole production line. Complete traceable test documents such as COA, HPLC chromatograms and mass spectrum identity verification reports can be provided for each batch, ensuring stable molecular composition and highly repeatable experimental performance between different batches. This product is strictly limited to in vitro laboratory testing and academic research activities only.

Ultra-high Purity & Complete Cyclic Molecular Structural Stability
Adopting multi-stage chromatographic separation and low-temperature sterile vacuum lyophilization processes, the product overall purity reaches above 99%. HPLC, mass spectrometry and full-length peptide sequencing are adopted for full batch identity verification. Vacuum freeze-drying technology effectively locks intact cyclic peptide spatial structure and prevents disulfide bond breakage or molecular denaturation, delivering accurate, stable and reproducible experimental data for long-cycle neuroendocrine cell research projects.
Fast Dissolution & Simple Laboratory Operation
The fluffy loose lyophilized powder dissolves rapidly in all conventional lab aqueous solvents without extra solubilizing additives. Operators can conveniently prepare high-concentration stock solutions and working diluents, fully matching daily operation demands of cell incubation, receptor binding affinity detection and diversified in vitro biochemical analysis experiments.
Unique Cyclic Nonapeptide Research Value
With stable intramolecular disulfide cyclic structure, this polypeptide shows specific binding selectivity to corresponding target receptors. It is the standardized experimental sample for studying cyclic peptide folding characteristics, ligand-receptor recognition mechanisms and downstream neuroendocrine signal activation kinetics, covering multiple cutting-edge professional directions of neuropeptide research.
Comprehensive Traceable Quality Document System
Customers can apply for a full set of supporting certification materials on demand, including Certificate of Analysis, HPLC chromatogram records, mass spectrum identification data and microbial limit test reports. All production flows follow unified manufacturing specifications for biological laboratory peptide reagents, meeting quality access standards of research institutions in various regions worldwide.
Excellent Long-Term Low-Temperature Storage Stability
Equipped with light-blocking and moisture-proof fully sealed vial packaging, the product can maintain intact molecular conformation and stable biochemical properties for 24 months under -20°C storage environment. The prepared aqueous solution also keeps steady within the valid storage period, adapting to both short-term rapid detection tests and continuous long-cycle neuroendocrine cell culture research.
