Description

TNF-α is secreted by macrophages, monocytes, neutrophils, T-cells, and NK-cells. Many transformed cell lines also secrete TNF-α. Monomeric mouse TNF-α is 156 amino acid protein (N-glycosylated) with a reported molecular weight of 17.5 kD protein. TNF-α forms multimeric complexes; stable trimers are most common in solution. A 26 kD membrane form of TNF-α has also been described. TNF-α binding to surface receptors elicits a wide array of biologic activities including: cytolysis and cytostasis of many tumor cell lines in vitro, hemorraghic necrosis of tumors in vivo, increased fibroblast proliferation, and enhanced chemotaxis and phagocytosis in neutrophils. The TN3-19.12 antibody reacts with mouse, rat, and rabbit tumor-necrosis factor-α (TNF-α) proteins. The TN3-19.12 antibody can neutralize the bioactivity of natural or recombinant TNF-α.

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µl volume or 100 µl of whole blood. It isrecommended that the reagent be titrated for optimalperformance for each application.

Application Notes

ELISA or ELISPOT Capture1: The Ultra-LEAF™ Purified TN3-19.12 antibody is useful as the capture antibody in a sandwich ELISA or ELISPOT assay, when used in conjunction with biotinylated Poly5160 antibody (Cat. No. 516003) as the detecting antibody for detecting mouse/rat TNF-a. The Ultra-LEAF™ purified antibody is suggested for ELISPOT capture.

Clone TN3-19.12 has been shown to neutralize murine TNF-a and cross reacts wtih mouse TFN-ß1. The Ultra-LEAF™ Purified antibody (Endotoxin < 0.01 EU/µg, Aside free, 0.2 µm filtered) is recommended for neutralization (Cat. Nos. 506109 - 506114).
