| 目标/特异性 | Detects human TNF-alpha in direct ELISAs and Western blots. In direct ELISAs, approximately 25‑50% cross‑reactivity with recombinant porcine TNF‑ alpha and recombinant rhesus macaque TNF-alpha is observed but no cross-reactivity with recombinant cotton rat TNF‑ alpha, recombinant rat TNF‑ alpha, recombinant human (rh) LT alpha 1/ beta 2, rhLT alpha 2/ beta 1, rhAPRIL, rhBAFF, rhEDA‑A2, recombinant mouse EDA, rhFas Ligand, rhLIGHT, rhOX40 Ligand, rhTRAIL, rhTRANCE, rhTWEAK, or rhVEGI is observed. |
| 使用方法 | Immunocytochemistry: 3-25 µg/mL Neutralization: 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 0.5 μg/mL actinomycin D |

| 背景 | TNF-alpha 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. |

TNF‑ alpha in Human PBMCs. TNF‑ alpha was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Recombinant Mouse Anti-Human TNF‑ alpha Monoclonal Antibody (Catalog # MAB2101R) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Cytotoxicity Induced by TNF-alpha and Neutralization by Human TNF-alpha Antibody. Recombinant Human TNF-alpha (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-alpha (0.75 ng/mL) is neutralized (green line) by increasing concentrations of Recombinant Human TNF-alpha Monoclonal Antibody (Catalog # MAB2101R). The ND50 is typically 0.01-0.06 μg/mL in the presence of the metabolic inhibitor actinomycin D (0.5 μg/mL). |
