Mouse TNF ELISA Kit standard curve

Product Info

• Predicted Species Reactivity: Mouse
• Application: ELISA
• ELISA Kit Detection Method: Colorimetric, OD450 nm
• ELISA Kit Duration: ~ 3 Hours
• ELISA Kit Principle: Aviva's mouse TNF alpha ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from hamster specific for TNF alpha has been precoated onto 96-well plates. Standards (E.coli,L80-L235) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for TNF alpha is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The absorbance of yellow is proportional to the mouse TNF alpha amount of sample captured in plate.

  Notes: 1. To inspect the validity of experiment operation and the appropriateness of sample dilution proportion, pilot
  experiment using standards and a small number of samples is recommended.
  2. The TMB Color Developing agent is colorless and transparent before using, contact us freely if it is not the case.
  3. Before using the Kit, spin tubes and bring down all components to the bottom of tubes.
  4. Duplicate well assay is recommended for both standard and sample testing.
  5. Don’t let 96-well plate dry, for dry plate will inactivate active components on plate.
  6. Don’t reuse tips and tubes to avoid cross contamination.
  7. To avoid to use the reagents from different batches together.
  8. In order to avoid marginal effect of plate incubation due to temperature difference ( reaction may be stronger in the
  marginal wells), it is suggested that the diluted ABC and TMB solution will be pre-warmed in 37C for 30 min before
  using.
  Background: Tumor necrosis factor-alpha (TNF-alpha, or TNF) is secreted by macrophages in response to inflammation, infection and cancer.Mouse 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. Mouse 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 Mouse tumor cell lines. The Mouse 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 Mouse chromosome 6.
