PRODUCT OVERVIEW

Oxytocin (nonapeptide, cyclic) is a reference ligand for OXTR widely used to interrogate Gq/PLC–Ca²⁺ and downstream ERK/MAPK signaling in receptor-positive cell models. Its compact sequence and robust literature record make it a dependable control for receptor-binding, functional readouts (e.g., intracellular Ca²⁺ flux), and method development in analytical labs. Peptide Tech pairs high analytical confirmation (MS/HPLC) with cold-chain fulfillment to protect peptide integrity from our facility to your bench.

POTENTIAL APPLICATIONS IN RESEARCH

• GPCR signaling dissection in OXTR-expressing cell lines, mapping PLC–IP₃–Ca²⁺ flux and ERK/MAPK activation via reporter assays, Westerns, or live-cell imaging. (PMC, PubMed)
• Radioligand or competition-binding assays to quantify OXTR affinity/selectivity and derive Kd/Ki values for candidate ligands or tool compounds. (PubMed)
• 3D spheroid/phenotypic models evaluating OXTR-mediated morphological responses and cell-level signaling outcomes under controlled in-vitro conditions. (PMC)
• Analytical method development and validation (e.g., LC–MS/MS, RIA/ELISA) for peptide detection, extraction recovery, matrix effects, and quantitation performance. (PMC)
• Calcium-imaging workflows (e.g., ratiometric dyes or GECIs) to benchmark ligand-evoked Ca²⁺ transients downstream of OXTR activation. (PMC)

FAQ

• Is this Oxytocin intended for human use?
  No. It is sold strictly as RUO—not for human or animal use, ingestion, diagnostic, or therapeutic purposes.
• What purity do you provide?
  Each 5 mg vial is ≥99% by HPLC with MS identity confirmation and third-party testing; see the lot-matched COA via QR.
• How should I reconstitute it?
  Use sterile water or compatible aqueous buffer; gently invert until dissolved. Filter through 0.22 µm if your assay requires sterility. Avoid multiple freeze–thaw cycles by aliquoting.
• What assays is Oxytocin commonly used in?
  Typical in-vitro uses include OXTR binding, Ca²⁺ flux/PLC pathway readouts, ERK/MAPK signaling studies, and analytical method validation (e.g., LC–MS, RIA). (See citations above.)
