Product Information

• Name: Chemotactic Peptide
• Synonyms: For-Met-Leu-Phe FMLP
• Brand: Biosynth
• Description: Chemotactic peptides are peptides that possess chemotactic properties, which means they attract cells. One well-known chemotactic peptide is For-Met-Leu-Phe (FMLP) and is a chemoattractant for phagocytic leukocytes and neutrophils. During the acute inflammatory response chemotactic factors activate neutrophils which have seven transmembrane G-protein coupled receptors. FMLP bind to these G-protein coupled receptors on the surface of neutrophils and activate NF- κB, MAPK and PI3K pathways. In particular FMLP is known to induce Interleukin-8 (IL-8) which is responsible for both tissue damage and the pathogenesis of inflammatory processes resulting from neutrophils. Chemotactic peptide have been used to study the function of polymorphonuclear leukocytes and other white blood cells in inflammation. Chemotactic peptides are often used as fluorescent probes to measure intracellular metabolic responses to chemoattractant stimulation.
