Human TNFβ ELISA Kit
Human TNFβ ELISA Kit
Application: For quantitative detection of TNFβ in human serum, plasma, body fluids, tissue lysates or cell culture supernates.
Introduction: Tumor necrosis factor-beta (TNF-beta), previously called lymphotoxin-alpha(LTA), is a member of the tumor necrosis factor family , is a cytokine produced by lymphocytes. It is a glycoprotein with a relative molecular mass (Mr) of 60,000-70,000. LTA is highly inducible, secreted, and exists as homotrimeric molecule. It forms heterotrimers with lymphotoxin-beta which anchors lymphotoxin-alpha to the cell surface. LTA mediates a large variety of inflammatory, immunostimulatory, and antiviral responses. It is also involved in the formation of secondary lymphoid organs during development and plays a role in apoptosis.
Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-P- Cadherin polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-TNFβ polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were 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 density of yellow is proportional to the TNFβ amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of TNFβ can be calculated.
Storage and Expiration: Store at 2-8℃ for 6 months, or at -20℃ for 12 months.
Range: 62.5 pg/ml - 4000 pg/ml
Sensitivity: < 5 pg/ml
