Application Details

Sample Volume: 100 μL

Plate: Pre-coated

Protocol: The microtiter plate provided in this kit has been pre-coated with an antibody specific to IL-4. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for IL-4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain IL-4, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm 2 nm. The concentration of IL-4 in the samples is then determined by comparing the O.D. of the samples to the standard curve. 2

Target Details for IL-4

Target: IL-4 (IL4) (Interleukin 4 (IL4))

Alternative Name: Il4

Background: Interleukin 4 (IL-4) is a pleiotropic cytokine produced primarily by activated T lymphocytes,mast cells and basophils . IL-4 has multiple immune response-modulating functions on a variety of cell types. It is an important regulator of isotype switching, inducing IgE production in B lymphocytes. It is an important modulator of the differentiation of precursor T helper cells to the Th2 subset that mediates humoral immunity and modulates antibody production. In addition, IL-4 has also been shown to have anti-tumor activity both in vivoand in vitro. The biological effects of IL-4 are mediated by specific cell surface receptor complexes. One type of functional IL-4 receptor complex consists of the IL-4-binding subunit (IL-4 R) and a second chain, designated the common c chain because it has also been identified as a component of the receptor complexes for IL-2, IL-7, IL-9 and IL-15. A second type of functional IL-4 receptor complex, consisting of the IL-4 R and the recently cloned IL-13 R, has also been proposed. Although IL-4 R does not bind IL-13 directly, it has been shown to complex with the low-affinity IL-13 R to form the functional high-affinity receptor complex for IL-13.
