Description

Oxytocin, Lys(8)- CAS NO 4273-93-2 is a synthetic analogue of the neuropeptide hormone oxytocin, specifically modified at the eighth position with a lysine residue. This modification is of significant interest for research into the structure-activity relationships of oxytocin and its receptor interactions. It serves as a critical tool compound for biochemical and pharmacological studies in neuroscience and endocrinology. Researchers in pharmaceutical development and academic institutions utilize this peptide to explore new therapeutic pathways.

Application

• Neuroscience Research: Investigation of oxytocin receptor (OXTR) binding, signaling pathways, and neurophysiological effects.
• Pharmacological Studies: Used as a reference standard or probe to study the impact of specific amino acid substitutions on peptide potency and selectivity.
• Endocrinology Research: Exploration of the role of oxytocin analogues in social behavior, stress response, and reproductive functions.
• Drug Discovery: Serving as a lead compound or intermediate in the development of novel peptide-based therapeutics targeting the oxytocin system.
• Biochemical Assays: Utilization in competitive binding assays (e.g., ELISA, RIA) and functional cell-based assays to characterize receptor interactions.
• Academic & Institutional Research: Fundamental research tool in university and government laboratories for studying peptide hormone biology.

Quality Control

Our Oxytocin, Lys(8)- is produced under stringent conditions to ensure high purity and batch-to-batch consistency, suitable for sensitive research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to rigorous quality testing protocols, and specifications can be aligned with research-grade or higher standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. This product is hygroscopic (moisture-sensitive) and should be allowed to equilibrate to room temperature in a desiccator before opening to prevent condensation and degradation. For long-term storage, consider under an inert atmosphere.
