Description

Acth (25-39) CAS NO 11138-17-3 is a synthetic peptide fragment corresponding to the 25-39 sequence of the adrenocorticotropic hormone (ACTH). This high-purity peptide is critical for research and development in endocrinology and neurobiology, serving as a valuable 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 disorders and central nervous system research.

Application

• Biomedical Research: Used as a reference standard and active agent in studies of the hypothalamic-pituitary-adrenal (HPA) axis.
• Pharmacological Studies: Investigation of ACTH receptor binding, steroidogenesis, and related metabolic processes.
• Neuroendocrine Research: Exploration of the role of ACTH fragments in brain function, behavior, and stress response.
• Diagnostic Development: Potential use in the development of immunoassays and diagnostic kits for endocrine function.
• Peptide Chemistry: Serves as a building block or intermediate in the synthesis of longer, modified peptide sequences for novel therapeutic candidates.

Quality Control

Our Acth (25-39) is manufactured under strict quality systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). We provide a comprehensive Certificate of Analysis (COA) with each shipment, detailing all test results against stringent in-house specifications to ensure batch-to-batch consistency and reliability for your critical research applications.

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). For long-term storage, consider desiccant and under an inert atmosphere. Allow the vial to reach room temperature before opening to minimize moisture uptake.
