Rat Nerve growth factor,NGF ELISA kit
Purpose
This kit allows for the determination of NGF concentrations in Rat serum, blood plasma, and other biological fluids.
Principle of the assay
The kit assay Rat NGF level in the sample，use Purified Rat NGF antibody to coat microtiter plate wells, make solid-phase antibody, then add NGF to wells, Combined NGF 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 NGF in the samples is then determined by comparing the O.D. of the samples to the standard curve.
