Detects human TNF-alpha in direct ELISAs. In direct ELISAs, approximately 50% cross-reactivity with recombinant rhesus macaque TNF-alpha is observed and no cross-reactivity with recombinant cotton rat, mouse, rat, or porcine TNF-alpha is observed. It shows no cross-reactivity with recombinant human (rh) APRIL, rhBAFF, rhEDA‑A2, rhFas Ligand, rhGITR Ligand, rhLIGHT, rhOX40 Ligand, rhRANK Ligand, rhTNF-beta, rhTRAIL, rhTRANCE, rhTWEAK, or rhVEGI.
Monoclonal Mouse IgG1 Clone # 1825
Protein A or G purified from ascites
E. coli-derived recombinant human TNF-alpha Gly57-Leu233 Accession # P01375
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize TNF‑ alpha -induced cytotoxicity in the L‑929 mouse fibroblast cell line. Matthews, N. and M.L. Neale (1987) in Lymphokines and Interferons, A Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 221. The Neutralization Dose (ND50) is typically 0.01-0.06 µg/mL in the presence of 0.75 ng/mL Recombinant Human TNF‑ alpha and 1 µg/mL actinomycin D.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Cytotoxicity Induced by TNF‑ alpha and Neutralization by Human TNF‑ alpha Antibody.
Recombinant Human TNF‑ alpha (Catalog # 210-TA) induces cytotoxicity in the the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line). Cytotoxicity elicited by Recombinant Human TNF‑ alpha (0.75 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human TNF‑ alpha Monoclonal Antibody (Catalog # MAB210). The ND50 is typically 0.01‑0.06 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

TNF-alpha, designated TNFSF2, is a trimeric glycoprotein active in both membrane bound and secreted forms. TNF-alpha is produced by several lymphoid cells as well as by astrocytes, endothelial cells, and smooth muscle cells. TNF-alpha binds to TNF RI and TNF RII present on virtually all cell types where it triggers the activation of multiple signal transduction pathways and modulates the expression of a wide variety of genes.
