Description

α-Msh (11-13) is a specific, high-purity peptide fragment derived from the α-melanocyte-stimulating hormone (α-MSH). This compound is critical for advanced biochemical research and development, offering a precise tool for studying melanocortin receptor signaling pathways. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and biotechnology companies focused on dermatology, inflammation, and metabolic disorders.

Application

• Biomedical Research: As a reference standard and active agent in studies of melanocortin receptors (MC1R, MC3R, MC4R, MC5R).
• Drug Discovery: Used in high-throughput screening (HTS) assays to identify and characterize novel agonists or antagonists for therapeutic development.
• Dermatology Studies: Investigation of skin pigmentation mechanisms, anti-inflammatory effects, and potential applications in vitiligo or melanoma research.
• Neuroscience: Research into the role of α-MSH fragments in feeding behavior, energy homeostasis, and neuroinflammatory responses.
• Peptide Chemistry: Serving as a building block or intermediate for the synthesis of longer, modified peptide analogs.
• In Vitro Diagnostics (IVD): Potential use in the development of immunoassays and biochemical test kits.
