Lipoxin A4 (LXA4; Item No. 90410) is a part of the specialized pro-resolving mediator (SPM) family of polyunsaturated fatty acid (PUFA) metabolites.{35079} It is formed from arachidonic acid through double lipoxygenase-catalyzed reactions initiated by either 5-lipoxygenase (5-LO) followed by 12-LO/15-LO, with a leukotriene A4 (LTA4) intermediate, or by 15-LO followed by 5-LO, with 15(S)-HETE and 5(S)-Hp-15(S)-HETE intermediates. The generation of LXA4 typically requires transcellular metabolism of arachidonic acid.{35079,35339} For example, LTA4 that is synthesized in neutrophils by 5-LO is metabolized to LXA4 in platelets by 12-LO.{35339} LXA4 is released during the resolution phase of inflammation and binds to the G protein-coupled LXA4 receptor (ALX)/formyl peptide receptor (FPR2), which is located on leukocytes, and induces cell type-specific signaling.1 In macrophages, it activates phosphatidylinositol 3-kinase (PI3K) and AKT, stimulates non-phlogistic phagocytosis of apoptotic leukocytes, and inhibits apoptosis to prolong the phagocytotic phase.{11078,35388} In neutrophils, it inhibits chemotaxis and transmigration and inhibits production of LTB4 (Item No. 20110).{35389} Cayman’s LXA4 ELISA Kit is a competitive assay which can be used for quantification of LXA4. This assay has been tested in urine, serum, and plasma. The ELISA typically displays an IC50 (50% B/B0) of approximately 200 pg/ml and a detection limit (80% B/B0) of approximately 50 pg/ml.

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
