Uses
Interleukin-4 from mouse has been used:
- as a component of cell culture media for class switch recombination assay
- to study its therapeutic benefits for mucosal healing
- as a pioglitazone or new peroxisome proliferator-activated receptor agonist (GQ-11)
Biochem/physiol Actions
Interleukin-4 (IL-4) is a lymphokine with profound effects on the growth and differentiation of immunologically competent cells. IL-4 is also known as B cell stimulatory factor-1 (BSF-1), T cell growth factor-2 (TCGF-2) and mast-cell growth factor-2 (MCGF-2). Inhibits VEGF-induced and FGF-Basic-induced angiogenesis. IL-4 is a complex glycoprotein released by a subset of activated T cells. Treatment of IL-4 with specific glycosidases yields an active polypeptide. Human and mouse IL-4 share 50% amino acid sequence homology, but their biological actions are species-specific.
Description
Interleukin-4 Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 120 amino acids and having a molecular mass of 13500 Dalton.
The IL-4 is purified by proprietary chromatographic techniques.
Background
Interleukin-4 is a pleiotropic cytokine produced primarily by activated T lymphocytes, basophils and mast cells. Multiple immune response-modulating functions are performed by IL-4 on a variety of cell types and it has an important role in the regulator of isotype switching, induction of IgE production in B lymphocytes and differentiation of precursor T helper cells. IL-4 binds to both membrane-bound and secreted soluble IL-4 receptors.
