Abcam’s IL-12 P40 Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human IL-12 P40 in serum (Human IL-12 p40 concentration is pretty low in normal serum/plasma, it may not be detected in this assay), plasma and cell culture supernatants.
This assay employs an antibody specific for Human IL-12 P40 coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-12 P40 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human IL-12 P40 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of IL-12 P40 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Optimization may be required with urine samples.
