Mastoparan X（Cat No.:I042551）is a peptide derived from the venom of the hornet Vespa species, known for its ability to activate G-protein-coupled receptors (GPCRs) and induce cellular responses such as the release of histamine and other inflammatory mediators. As a potent activator of phospholipase C, Mastoparan X promotes cell signaling pathways involved in immune responses, inflammation, and cell proliferation. Its ability to trigger mast cell degranulation makes it a useful tool for studying allergic reactions, immune system functions, and potential therapeutic targets for inflammation-related disorders and autoimmune diseases.
