Rat Tumor necrosis factor α,TNF-α ELISA KIT 
Purpose
This kit allows for the determination of TNF-α concentrations in Rat serum, blood plasma, and other biological fluids.
Principle of the assay
The kit assay Rat TNF-α level in the sample,use Purified Rat TNF-αantibody to coat microtiter plate wells, make solid-phase antibody, then add TNF-α to wells, Combined TNF-α antibody which With HRP labeled,become antibody-antigen- enzyme-antibody complex, after washing Completely, Add TMB substrate solution, TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of TNF-α in the samples is then determined by comparing the O.D. of the samples to the standard curve.

PRECISION
 
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
 
CV(%) = SD/mean X 100
Intra-Assay: CV<8%
