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.

IP, WB - Reported in the literature, not verified in house - Recommended Usage
-
Each lot of this antibody is quality control tested by ELISA assay. For ELISA capture applications, a concentration range of 2-6 µg/ml is recommended. To obtain a linear standard curve, serial dilutions of mouse TNF-α recombinant protein ranging from 500 to 4 pg/ml are recommended for each ELISA plate or serial dilutions of rat TNF-α recombinant protein ranging from 2500 to 20 pg/ml are recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance 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). - Application References
