Scientific Data Images for Human TNF-alpha Antibody

Cytotoxicity Induced by TNF‑ alpha and Neutralization by Human TNF-alpha Antibody.

Cytotoxicity Induced by TNF‑ alpha and Neutralization by Human TNF-alpha Antibody.

Recombinant Human TNF-a (Catalog # 210-TA) induces cytotoxicity in the L-929 mouse fibroblast cell line in a dose-dependent manner (orange line). Cytotoxicity elicited by Recombinant Human TNF-a (1.5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human TNF-a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-210-NA). The ND50 is typically 0.01-0.06 µg/mL.
TNF-a antibody in Human PBMCs by Immunocytochemistry (ICC).

TNF‑ alpha in Human PBMCs.

TNF-a was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human TNF-a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-210-NA) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: TNF-alpha

Tumor necrosis factor alpha (TNF-alpha, TNF- alpha, TNFA ), 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, immune system development, apoptosis, and lipid metabolism. TNF- is produced by several lymphoid cells as well as by astrocytes, endothelial cells, and smooth muscle cells. Human TNF-alpha consisits 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-alpha shares 97% aa sequence identity with rhesus and 71%-92% with bovine, canine, cotton rat, equine, feline, mouse, porcine, and rat TNF-alpha. TNF-alpha is produced by a wide variety of immune, epithelial, endothelial, and tumor cells. TNF-alpha is assembled intracellularly to form a noncovalently linked homotrimer which is expressed on the cell surface. Cell surface TNF-alpha can induce the lysis of neighboring tumor cells and virus infected cells, and it can generate its own downstream cell signaling following ligation by soluble TNFR I. Shedding of membrane bound TNF-alpha by TACE/ADAM17 releases the bioactive cytokine, a 55 kDa molecular weight soluble trimer of the TNF-alpha extracellular domain. TNF-alpha binds the ubiquitous 55-60 kDa TNF RI and the hematopoietic cell-restricted 80 kDa TNF RII, both of which are also expressed as homotrimers present on virtually all cell types. Both type I and type II receptors bind TNF-alpha with comparable affinity, although only TNF RI contains a cytoplasmic death domain which triggers the activation of apoptosis. Soluble forms of both types of receptors are released and can neutralize the biological activity of TNF-alpha.
