Interleukin-4 (IL-4) is a T cell derived chemokine that stimulates the Th2 mediated immune response and proliferation of B cells. The effects of IL-4 are mediated by two types of receptors, type I receptor consisting of IL-4Rα and common γ chain and type II receptor composed of IL-4Rα and IL-13Rα1. The signaling stimulated by IL-4 leads to activation of JAK/STAT6 and IRS-mediated PI3K/Akt pathway. Through these pathways, IL-4 is responsible for endocytic activity of macrophages, chemotaxis of leukocytes in response to inflammation, angiogenesis and regulation of nitric oxide metabolism in macrophages. Anti-tumor effects of IL-4 have been reported in cancers of breast, liver and renal cells. Anti-Interleukin-4 specifically recognizes human interleukin-4. The antibody shows no cross reactivity with rmIL-4 and rrIL-4.
The antibody will neutralize the biological activity of recombinant human IL-4, but not recombinant mouse IL-4.
recombinant human IL-4.
Anti-Interleukin-4 antibody may be used for immunoblotting at a working concentration of 0.1-0.2 μg/ml. For ELISA, a working concentration of 0.5-1.0 μg/ml is recommended. The antibody may be used for immunohistochemistry of cultured cells or tissue sections at a working antibody concentration of 0.5-5 μg/ml. The antibody is suitable for neutralization assay; ND50 is 0.02-0.1 μg/ml. Anti-IL-4 antibody was used for immunohistochemistry and ELISA using cervicovaginal tissue sections and cervicovaginal extracts of Belgium white rabbits.
