Mouse TNF-alpha ELISA Kit

The Mouse Tumor Necrosis Factor-alpha (TNF-α) ELISA Kit is designed for the quantitative detection and measurement of mouse TNF-α in biological fluids such as serum, plasma, and cell culture supernatants. TNF-α is primarily produced by activated T cells and macrophages in response to inflammation or infection, but is also produced by B cells, NK cells, mast cells, neutrophils, dendritic cells, microglia, endothelial cells, smooth muscle cells, cardiomyocytes, and fibroblasts. TNF-α is a pro-inflammatory cytokine and stimulates anti-tumor responses in vitro.

The assay is based on the sandwich ELISA method, in which samples are added to ELISA strip plates pre-coated with capture antibodies specific for the cytokine. The captured cytokine is detected by addition of a biotinylated detection antibody, followed by streptavidin-horseradish peroxidase, which binds the biotinylated antibody. Addition of the chromogenic enzyme substrate 3,3’,5,5’ tetramethylbenzidine (TMB) results in a colored product with an intensity directly proportional to the concentration of cytokine in the sample. The concentration of the cytokine is determined by comparison to a serial dilution of the cytokine standard analyzed in parallel.
