ELISA kit description
GENTAUR's human TNF alpha ELISA test is a ready to use ELISA kit. We use a monoclonal from mouse specific for TNF alpha has been precoated onto 96-well plates. Standards (E.coli,V77-L233) and your samples are measured with a biotin conjugated polyclonal from goat specific for TNF alpha will than be washed with PBS. The colour reaction with TMB on HRP will colour the well from blue to yellow with the stop solution. The more human TNF alpha in your sample the higher the ELISA signal will be compared to this elisa's standard curve.

How the elisa works
Sample the amount of 100ul/well of the standard solution at 1000 pg per ml, 500, 25, 125, 62.5, 31.25, 15.6 pg/ml human TNF alpha standard solutions into the precoated 96-well plate. Add 0.1ml of the sample diluent buffers into the control well (Zero well). Add 0.1ml of each properly diluted sample of human cell culture supernatant, serum or plasma(heparin, EDTA, citrate) to the ELISA plate. Keep in mind that each human TNF alpha standard solution and each sample be measured in duplicate.

More gene info
Tumor necrosis factor-alpha(TNF-alpha, or TNF) is secreted by macrophages in response to inflammation, infection and cancer. Human Tumor Necrosis Factor(TNF) and Lymphotoxin(TNF-beta) are cytotoxic proteins which have similar biological activities and share 30% amino acid homology. TNF-alpha is produced by monocytes, which can stimulate endothelial cells to produce the multilineage growth factor granulocyte-macrophage colony-stimulating factor and extend the role of this immunoregulatory protein to the regulation of hematopoiesis in vitro. TNF is a soluble protein that causes damage to tumor cells but has no effect on normal cells. Human TNF has been purified to apparent homogeneity as a 17.3-kilodalton protein from HL-60 leukemia cells and has showed cytotoxic and cytostatic activities against various human tumor cell lines. The human TNF cDNA is 1585 base pairs in length and encodes a protein of 233 amino acids. The mature protein begins at residue 77, leaving a long leader sequence of 76 amino acids. TNF-alpha has been mapped to human chromosome 6.

Gene
Tumor necrosis factor (TNFa, tumor necrosis factor alpha, TNFα, cachexin, or cachectin) is a cell signaling protein (cytokine) involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction. It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. TNFb or TNF beta also bin on TNF receptors for Th1 activation.

Technique
ELISA kit, ELISA, ELISAs Enzyme-linked immunosorbent assay 90320007 SNOMED code are used by the medical researcher for detection of human, mouse, … proteins are supplied in coated 96 well plates to be stored at +4°C. ELISA test kits can be sandwich ELISA. In sandwich ELISAS Enzyme-linked immunosorbent assay 9we use captor and detector antibodies. In single antibody ELISAs the antigen is coated and only a detector antibody is used. Traditional competition antigen ELISAs are coated with a captor antibody and a competitive antigen is labelled with the chromogen. In this case the ratio on your graph will be inverse proportional with the antigen present in your sample.
