Precision
Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
             
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of rabbit TNFα in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
  Sample Serum(n=4)  
1:1 Average % 86

Q&A and Customer Reviews

  • Tested application: ELISA
    Test sample: Tissue homogenate (Liver and intestine)
    Species: Rabbit
    Review:I tried the kit to determine the best working dilution (starting concentration 100mg/mL). In the case of liver the best result was obtained with 5x-10x dilution, and for intestine the best results were using undiluted sample to 2x dilution.

Target Data

Function 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.; FUNCTION
Gene References into Functions
  1. TUNEL staining was positively correlated with TNF-a protein expression. Our findings suggest that apoptosis can be induced in the vocal fold epithelium after 120min of modal intensity phonation. In contrast, shorter durations of vibration exposure do not result in apoptosis signaling. PMID: 27577014
  2. Inflammatory factors such as TNF-alpha can stimulate MMP-2/9 activity in corneal epithelium cells. This may be a potential manipulating mechanism of MMP expression in the pathogenesis of corneal diseases. PMID: 26125840
  3. The JNK pathway plays an important role in mechanical ventilation-stimulated TNF-alpha expression in alveolar macrophages, but the injury-stimulated IL-8 expression may be regulated by other signaling pathways. PMID: 24070709
  4. The TNFalpha-evoked Cl- current. PMID: 24084720
  5. IL-1beta and TNF-alpha expression increases significantly during acute lung injury. Ambroxol combined with low-dose heparin inhibits teh release of IL-1beta and TNF-alpha. PMID: 21845882
  6. Hypercapnia increased expression of TNFa and decreased expression of NFKB in acute lung injury models. PMID: 21158126
  7. In the early stages of myocardial ischemia, bone marrow stem cells are mobilized and home to ischemic myocardium with a concomitant increase in expression of cytokines VEGF and TNFalpha. PMID: 20624659
  8. Ammonium perchlorate can increase gene expressions of types I, III collagens, TGF-beta(1) and TNF-alpha in lung of rabbits. PMID: 20937628
  9. TNFalpha may either be directly or indirectly involved in vascular damage following an embolic stroke. Moreover, TNFalpha may mediate some of the detrimental effects of tPA on the vascular compartment PMID: 17673188
