TNF ELISA Kit (Monkey)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Tumor Necrosis Factor Alpha (TNFa) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Tumor Necrosis Factor Alpha (TNFa) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

ATP-binding cassette, sub-family F (GCN20), member 1; cachectin; EGK_14705; TNF-a; TNF-ALPHA; TNLG1F; tumor necrosis factor; tumor necrosis factor (TNF superfamily, member 2) ; tumor necrosis factor alpha; tumor necrosis factor ligand 1F; tumor necrosis factor ligand superfamily member 2.

Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation.

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Tumor Necrosis Factor Alpha (TNFa) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Tumor Necrosis Factor Alpha (TNFa) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Tumor Necrosis Factor Alpha (TNFa), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Tumor Necrosis Factor Alpha (TNFa) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
