Rat Tumor necrosis factor α (TNF-α) ELISA Kit | KTE100065 from Abbkine.

Product Overwiew:

This Rat Tumor necrosis factor α (TNF-α) ELISA Kit employs a two-site sandwich ELISA to quantitate TNF-α.


TNFa is synthesized as a 26 kDa, type II transmembrane protein that is 233 amino acids in length. It contains a 30 amino acid (aa) cytoplasmic domain, a 26 aa transmembrane segment, and a 177 aa extracellular region. TNFa is assembled intracellularly to form a transmembrane, non-covalently-linked homotrimeric protein. The 157 aa residue soluble form of TNFa (sTNF-αis released from the C-terminus of the transmembrane protein through the activity of TNFa-converting enzyme (TACE), a membrane -bound disintegrin metalloproteinase. Rat cells known to express TNF-αinclude B cells, colonic columnar epithelial cells, NK and CD3 CD56 hepatic natural T cells, macrophages, monocytes and monocyte-derived dendritic cells, CD4 and CD8 T cells, mast cells, neutrophils, keratinocytes, plasma cells, and adipocytes.








This Rat Tumor necrosis factor α (TNF-α) ELISA Kit employs a two-site sandwich ELISA to quantitate TNF-α in samples. An antibody specific for TNF-α has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTNF-α present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TNF-α is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TNF-α bound in the initial step. The color development is stopped and the intensity of the color is measured.

Used for:


Kit components:

• Rat Tumor necrosis factor α microplate
• Rat Tumor necrosis factor α standard
• Rat Tumor necrosis factor α detect antibody
• Streptavidin-HRP
• Standard diluent
• Assay buffer
• HRP substrate
• Stop solution
• Wash buffer
• Plate covers

Features & Benefits:

Rat Tumor necrosis factor α (TNF-α) ELISA Kit has high sensitivity and excellent specificity for detection of Rat TNF-α. No significant cross-reactivity or interference between Rat TNF-α and analogues was observed.

Usage Notes:

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.

Storage buffer:
