The Quantikine Canine TNF-alpha Immunoassay is a 4.5 hour solid-phase ELISA designed to measure canine TNF-alpha in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant canine TNF-alpha and antibodies raised against the recombinant protein. Results obtained for naturally occurring canine TNF-alpha showed linear curves that were parallel to the standa...rd curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural canine TNF-alpha.

Tumor necrosis factor alpha (TNF-α), also known as cachectin and TNFSF2, is the prototypic ligand of the TNF superfamily. It is a pleiotropic molecule that plays a central role in inflammation, apoptosis, and immune system development. TNF-α is produced by a wide variety of immune and epithelial cell types. Human TNF-α consists of a 35 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 177 aa extracellular domain (ECD). Within the ECD, human TNF-α shares 97% aa sequence identity with rhesus and 71% - 92% with bovine, canine, cotton rat, equine, feline, mouse, porcine, and rat TNF-α. The 26 kDa type 2 transmembrane protein is assembled intracellularly to form a noncovalently linked homotrimer. Ligation of this complex induces reverse signaling that promotes lymphocyte costimulation but diminishes monocyte responsiveness.
Cleavage of membrane bound TNF-α by TACE/ADAM17 releases a 55 kDa soluble trimeric form of TNF-α. TNF-α trimers bind the ubiquitous TNF RI and the hematopoietic cell-restricted TNF RII, both of which are also expressed as homotrimers. TNF-α regulates lymphoid tissue development through control of apoptosis. It also promotes inflammatory responses by inducing the activation of vascular endothelial cells and macrophages. TNF-α is a key cytokine in the development of several inflammatory disorders. It contributes to the development of type 2 diabetes through its effects on insulin resistance and fatty acid metabolism.

I need to know about TNF-alpha antibody kits for mice.
We currently have two TNFalpha ELISA kits specific for mouse: catalog numbers KA0257 and NBP1-92670.
I would like to ask you for help. I need an antibody for Elisa to detect human TNF alpha in a supernatant from a cell culture (meaning supernatant after centrifugation of collected cell suspension from a plate well). Which of your antibodies against human tnf alpha would be suitable? I would like to buy only the primary antibody.
I would recommend catalog number NBP1-67821 or NB600-587; however, a full list of our anti-human TNF alpha antibodies suitable for use in ELISA can be found using this link.
I am interested in a TNF alpha antibody, cross reactive for human, rat and mouse (host species: rabbit). Could your product NBP1-19532 be used in western blotting applications? Or do you have a similar product in your catalog which could fit with my request?
The antibody you mention, NBP1-19532, has not yet been validated in Western blot. I would instead recommend either NBP1-67821 or NB600-587. These are both rabbit polyclonal antibodies that cross-reacts with human, mouse and rat and have been used in Western blotting.
Can your TNF-alpha products be used to treat TBI victims and therefore avoid the perispinal injections with Enbrel?
I am very sorry, but all of our products are for scientific research use only, and none are intended or approved for use in humans.
CD86 - I work in tandem with CD80 CD86 belongs to the immunoglobulin superfamily of proteins that drive innate and adaptive immune responses. It is an 80kD co-stimulatory molecule for the priming and activation of naive and memory T-cells, respectively. CD86 is expressed on activated ... Read full blog post.
