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 human TNF-α in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • Sample type: Serum
    Sample species: Human
    Review: Cell viability and cytotoxicity of PBMCs (e), IL-6 (f) and TNF-α(g) secretion levels with different incubation time. Temperature was 37.5 °C, MNP@DMSA concentration was 1.0 mg/mL, and incubation time was 120 minutes.
    PMID: 30390582
  • Sample type: Serum
    Sample species: Human
    Review: Concentrations of IL-6 and TNF-α in MNP@CTAB-BSA group maintain at normal level when the incubation time increases from 30 minutes to 180 minutes. Concentrations of IL-6 and TNF-α in MNP@CTAB group rise above the normal level with prolonged incubation time.
  • Sample type: Cell culture supernatant
    Sample species: Human
    Review: Same trend was observed in the concentrations of IL-1α, IL-6, IL-8 and TNF-α in cell culture supernatant.
    PMID: 30026098
  • Sample type: Cell culture supernatant after Lnc-DC silencing
    Sample species: Human
    Review: The ELISA data indicate that Lnc-DC silencing significantly decreased the concentration of TNF-α .
    PMID: 30202418
  • Sample type: Serum
    Sample species: Human
    Review:The main outcome measures in this study were circulating pro-inflammatory cytokine levels (TNF-α, IL-1B, IL-6, IL-10), urinary cortisol levels, beck depression inventory (BDI) score, weight and body mass index (BMI).
  • Sample type: Serum
    Sample species: Human
    Review: ELISA was used to analyze cytokines (TNF-α, IFN-γ, IL-2 and IL-6) expression after Jurkat and P116 cells were stimulated with anti-CD3/CD28 antibodies for 24 hours.
    PMID: 30639475

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. Impairs regulatory T-cells (Treg) function in individuals with rheumatoid arthritis via FOXP3 dephosphorylation. Upregulates the expression of protein phosphatase 1 (PP1), which dephosphorylates the key 'Ser-418' residue of FOXP3, thereby inactivating FOXP3 and rendering Treg cells functionally defective
Involvement in disease Psoriatic arthritis (PSORAS)
Subcellular Location Cell membrane, Single-pass type II membrane protein, SUBCELLULAR LOCATION: Tumor necrosis factor, membrane form: Membrane, Single-pass type II membrane protein, SUBCELLULAR LOCATION: Tumor necrosis factor, soluble form: Secreted, SUBCELLULAR LOCATION: C-domain 1: Secreted, SUBCELLULAR LOCATION: C-domain 2: Secreted
Protein Families Tumor necrosis factor family
