应用 | Neutralization |
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 | 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 0.015-0.06 µg/mL in the presence of 0.25 ng/mL Recombinant Human TNF‑ alpha and 1 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. |

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 (0.25 ng/mL) is neutralized (green line) by increasing concentrations of Human TNF‑ alpha Monoclonal Antibody (Catalog # MAB2101). The ND50 is typically 0.015-0.06 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL). |
