- Product Overview:
TNF ligand superfamily member 4 (TNFSF4), also known as OX40L, is a type II transmembrane protein and the cognate ligand of the T cell co-stimulatory TNF receptor TNFRSF4, also known as OX40.{57028,57029} TNFSF4 assembles into trimers, with each monomer possessing an approximately 132-amino acid extracellular domain comprised of a TNF homology domain followed by a C-terminal extension. It is upregulated in antigen-presenting cells, including B cells, macrophages, and dendritic cells, in response to antigen presentation, and is also expressed in mast cells, activated T cells, and certain endothelial cells.{57029} Binding of a TNFSF4 trimer to three TNFRSF4 monomers promotes T cell survival and memory, as well as an effector T cell phenotype, enhances cell mobility, and increases the production of effector cytokines. Polymorphisms in TNFSF4 are associated with susceptibility to systemic lupus erythematosus (SLE) and systemic sclerosis.{57030,57031} Cayman’s TNFSF4 Extracellular Domain (human, recombinant) protein can be used for ELISA. This protein is a disulfide-lined homodimer. The reduced monomer, comprised of TNFSF4 (amino acids 51-183) fused to mouse IgG1 Fc at its N-terminus, consists of 369 amino acids and has a calculated molecular weight of 42.1 kDa. As a result of glycosylation, the monomer migrates at approximately 50 kDa by SDS-PAGE under reducing conditions.
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.
