Recombinant human IL-4 (Cat.NO. HZ-1004) stimulates proliferation of TF-1 cell line (human erythroleukemic cell line) in a dose-dependent manner (blue curve, refer to bottom X-left Y). The activity of human IL-4 (0.5 ng/mL HZ-1004) is neutralized by mouse anti-human IL-4 monoclonal antibody 69005-1-Ig at serial dose (red curve, refer to top X-right Y). The ND50 is typically 200-500 ng/mL.
IL4 is a cytokine produced by CD4+ T cells in response to helminthes and other extracellular parasites. It promotes the proliferation and differentiation of antigen presenting cells. IL4 also plays a pivotal role in antibody isotype switching and stimulates the production of IgE. This cytokine has been applied in the treatment of autoimmune disorder like multiple myeloma, cancer, psoriasis, and arthritis. IL4 has also been extensively applied to inhibit detrimental effect of Th1. It may promote the growth of epithelial tumors by mediating increased proliferation and survival.
This antibody is used to Block/Neutralize IL4 protein.
