Rat LIF (Leukemia Inhibitory Factor) ELISA kit

This kit applies sandwich ELISA method for the quantitative detection of LIF (Leukemia Inhibitory Factor) in rat samples. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat LIF. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat LIF. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat LIF, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ±10nm. The concentration of Rat LIF in the samples is then determined by comparing the OD of the samples to the standard curve.
