Introduction | TNF-α, the prototypical member of the TNF protein superfamily, is a homotrimeric type-II membrane protein. Membrane-bound TNF-α is cleaved by the metalloprotease TACE/ADAM17 to generate a soluble homotrimer. Both membrane and soluble forms of TNF-α are biologically active. TNF-α is produced by a variety of immune cells including T cells, B cells, NK cells, and macrophages. Cellular response to TNF-α is mediated through interaction with receptors TNF-R1 and TNF-R2 and results in activation of pathways that favor both cell survival and apoptosis depending on the cell type and biological context. Activation of kinase pathways (including JNK, Erk1/2, p38 MAPK, and NF-κB) promotes the survival of cells, while TNF-α-mediated activation of caspase-8 leads to programmed cell death. TNF-α plays a key regulatory role in inflammation and host defense against bacterial infection, notably Mycobacterium tuberculosis. |

Reactivity | Rat |
Specificity | Detects rat TNF‑ alpha in direct ELISAs and Western Blots. In Western Blots, approximately 25% cross-reactivity with recombinant porcine TNF-alpha is observed and less than 1% cross-reactivity with recombinant human (rh) TNF-beta, rhTNF sRI, and rhTNF sRII is observed. In direct ELISAs, approximately 40% cross-reactivity with recombinant canine TNF-alpha, recombinant feline TNF-alpha, and recombinant rhesus macaque TNF-alpha is observed. Neutralizes the biological activity of rat TNF-alpha. This antibody will also neutralize the biological activity of murine TNF-alpha, but weak neutralization of rhTNF-alpha and no neutralization of rhTNF-beta was observed. |
