Further Information

Alternate Names/Synonyms:
Interleukin-4; B Cell Stimulatory Factor 1; BSF-1
Biological Activity:
Shows the biological function of the IL-4 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain.
EClass:
32160000
Endotoxin:
<0.06EU/µg protein (LAL test; Lonza).
Form (Short):
liquid
Formulation:
Lyophilized from 0.2µm-filtered solution in PBS.
Handling Advice:
Avoid freeze/thaw cycles.Centrifuge lyophilized vial before opening and reconstitution.
Long Description:
Protein. The extracellular domain of human IL-4 (aa 1-153) is fused to the N-terminus of the Fc region of a mutant human IgG1. Source: CHO cells. Endotoxin content: <0.06EU/µg protein (LAL test; Lonza). Lyophilized from 0.2µm-filtered solution in PBS. Purity: >98% (SDS-PAGE). Interleukin-4 (IL-4) is a cytokine produced by type 2 helper T cells, the Th2 cells. These cells tends to make a specific set of lymphokines including IL-4, IL-5, IL-6, IL-10, IL-13, IL-3 and GM-CSF and fail to produce IL-2, IFN-gamma, and lymphotoxin (TNF-beta). In addition, mast cells can produce IL-4. IL-4 exerts numerous effects on various hematopoietic cell types. On B cells, IL-4 promotes immunoglobulin class switching to IgE and IgG1 isotypes and upregulates MHC class II and CD23 expression. IL-4 promotes survival, growth, and differentiation of both T and B lymphocytes, mast cells and endothelial cells. In addition, IL-4 inhibits the production of TNF, IL-1, and IL-6 by macrophages.
