IL-4 is a pleiotropic cytokine that is produced by activated T cells mast cells and basophils. IL-4 elicits many different biological responses, but has two dominant functions. The first is regulating differentiation of naïve CD4+ T cell to the Th2 type. Th2 cells produce IL-4, IL-5, IL-10 and IL-13, which tend to favor a humoral immune response while suppressing a cell-mediated immune response controlled by Th1 cells. The second is regulating IgE and IgG1 production by B cells. The 8D4-8 antibody can neutralize the bioactivity of natural or recombinant IL-4.

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. The purified 8D4-8 has been tested by blocking fluorochrome conjugated 8D4-8 for intracellular cytokine staining. In order to obtain complete blocking results, a saturated amount of purified antibody (≤ 5.0 ug/million cells) should be used for incubation with target cells, prior to staining with fluorochrome conjugated antibody. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
Additional reported applications (for the relevant formats) include: ELISPOT Capture, neutralization, intracellular staining for flow cytometry, immunohistochemical staining, and immunoprecipitation.
