Description

Acth (17-39) CAS NO 11138-16-2 is a synthetic peptide fragment corresponding to amino acids 17-39 of the adrenocorticotropic hormone (ACTH). This high-purity peptide is critical for research and development in endocrinology and neurobiology, serving as a precise tool for studying hormone-receptor interactions and signaling pathways. It is primarily utilized by pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies focused on metabolic and stress-related disorders.

Application

• Biochemical Research: Used as a reference standard and active agent in studies of ACTH receptor binding and adrenal cortex stimulation.
• Pharmaceutical Development: Serves as a key intermediate or active pharmaceutical ingredient (API) in the development of diagnostic agents and therapeutic candidates targeting endocrine functions.
• In Vitro Diagnostics: Employed in the calibration and development of immunoassays and test kits designed to measure ACTH levels or related biomarkers.
• Neuroscience Studies: Applied in research investigating the role of ACTH fragments in brain function, behavior, and the stress response.
• Peptide Chemistry: Used as a building block or model compound in peptide synthesis and structure-activity relationship (SAR) studies.
