- Product Overview:
15-keto Prostaglandin E2-d4 (15-keto PGE2-d4) is intended for use as an internal standard for the quantification of 15-keto PGE2 (Item No. 14720) by GC- or LC-MS. 15-keto PGE2 is a metabolite of PGE2 (Item No. 14010) formed by 15-hydroxy prostaglandin dehydrogenase (15-PGDH).{2777} Unlike PGE2, 15-keto PGE2 does not bind effectively to the PGE2 receptors EP2 and EP4 expressed in CHO cells (Kis = 2.6 and 15 µM, respectively) or induce adenylate cyclase activity in the same cells (EC50s = 1.8 and >33 µM, respectively). However, it does bind to EP2 and EP4 in HEK cells expressing these receptors (IC50s = 0.117 and 2.82 µM, respectively), as well as induces cAMP formation (EC50s = 0.137 and 0.426 µM, respectively) and the transcriptional activity of ?-catenin/TCF in the same cells.{57866} 15-keto PGE2 inhibits CD3-CD28-MHC-I-induced proliferation of isolated human CD4+ T cells in a concentration-dependent manner.{57867} It also reduces mortality in a mouse model of LPS-induced sepsis when administered at a dose of 15 mg/kg.{57868}
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.
