Description

Somatostatin-22 is a synthetic cyclic tetradecapeptide analog of the endogenous hormone somatostatin, identified by CAS NO 73726-55-3. This compound is valued for its potent inhibitory effects on the secretion of growth hormone, insulin, and glucagon, making it a critical research and development tool. It is primarily utilized by pharmaceutical researchers, biotech companies, and academic institutions engaged in endocrinology, oncology, and metabolic disorder studies.

Application

• Pharmaceutical Research & Development: Used as a reference standard and active pharmaceutical ingredient (API) in the development of novel therapeutics targeting hormone-dependent conditions.
• Endocrinology Studies: Serves as a key biochemical tool to investigate the regulation of growth hormone, insulin, and glucagon secretion in vitro and in vivo.
• Oncology Research: Employed in studies exploring the role of somatostatin receptors in tumor growth inhibition and as a model compound for developing targeted cancer therapies.
• Metabolic Disorder Models: Utilized in preclinical research to create models for diabetes and acromegaly to test potential treatment efficacy.
• Biochemical Assay Development: Acts as a critical component in the development and validation of immunoassays and receptor-binding assays.
• Academic & Clinical Research: Provides a reliable peptide standard for fundamental research into neuroendocrine signaling pathways.

Quality Control

Our Somatostatin-22 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). We provide Certificates of Analysis (COA) detailing all specifications, ensuring traceability and compliance with research-grade standards. Stability studies are conducted to guarantee performance throughout the shelf life.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term storage, consider under an inert atmosphere.
