Mouse TNF-α (Tumor Necrosis Factor α) is a potent multifunctional cytokine that can exert regulatory, inflammatory, and cytotoxic effects on a wide range of normal lymphoid and non-lymphoid cells and tumor cells. TNF-α is secreted by macrophages, monocytes, neutrophils, T-cells (primarily CD4+ T cells), NK-cells, and many transformed cell lines. It exists as a soluble 17.5 kD protein and a 26 kD membrane-associated protein. The membrane form protein, but not the soluble form, is phosphorylated on serine residues. Dephosphorylation of the membrane form occurs by binding to soluble TNFRSF1A/TNFR1. TNF-α binding to surface receptors elicits a wide array of biologic activities including: cytolysis and cytostasis of many tumor cell lines in vitro, hemorrhagic necrosis of tumors in vivo, increased fibroblast proliferation, and enhanced chemotaxis and phagocytosis in neutrophils. TNF-α plays a critical role in many physiological and pathological conditions, including neurodegenerative diseases and cancer.
The BioLegend LEGEND MAX™ High Sensitivity Mouse TNF-α ELISA Kit is a Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) with a 96-well strip plate that is pre-coated with a monoclonal anti-mouse TNF-α capture antibody. The detection antibody is a biotinylated polyclonal anti-mouse TNF-α antibody. After washing away any unbound biotinylated detection antibody, a streptavidin-polymer HRP is used for detection. Streptavidin-Polymer HRP enhances the sensitivity of the kit, allowing for detection of low concentrations of TNF-α. This kit is specifically designed for the accurate quantitation of mouse TNF-α in serum, plasma, and cell culture supernatant. This kit is analytically validated with ready-to-use reagents.

Related FAQs
- In your LEGEND MAX™ ELISA Kits, there is a step that calls for washing the plates before adding sample. What is the purpose of this step?
-
We typically use a stabilizer for pre-coated plates. The additional washing step is designed to remove these components before you start the assay. If you do not perform the washing, the effect on assay performance is negligible.
- I have multiple LEGEND MAX™ ELISA kits that I want to run simultaneously. Can I use the same wash buffer for all the kits?
-
The wash buffer provided in all our LEGEND MAX™ kits is the same and the part numbers on the wash buffer bottles in these kits should be identical. For ELISA MAX™ Deluxe and ELISA MAX™ Standard Sets, we provide a recipe for the wash buffer on each kit’s technical data sheet. This recipe is the same for all ELISA MAX™ sets.
- For some of your ELISA kits, why do my serum samples require dilution with assay buffer?
-
In some cases, dilution with assay buffer is required to minimize the matrix difference between the samples and the standards to achieve better accuracy.
