• Cat.No.: IL4-409H
• Product Overview: Interleukin-4 Human Recombinant produced in E.Coli is single, a non-glycosylated, Polypeptide chain containing 150 amino acids fragment (25-153) and having a total molecular mass of 19.62kDa with an amino-terminal hexahistidine tag. The IL-4 is fused to 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.

Specification

• Species: Human
• Source: Human
• Tag: His
• Protein Length: 25-153 a.a.
• Description: 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.
• Form: Interleukin-4 His-Tag is supplied in 1x PBS, 50% glycerol.
• Purity: Greater than 95.0% as determined by SDS-PAGE.
• Physical Appearance: Sterile Filtered clear solution.
• Amino acid sequence: MGSSHHHHHH SSGLVPRGSH MHKCDITLQE IIKTLNSLTE QKTLCTELTV TDIFAASKNT TEKETFCRAA TVLRQFYSHH EKDTRCLGAT AQQFHRHKQL IRFLKRLDRN LWGLAGLNSC PVKEANQSTL ENFLERLKTI MREKYSKCSS.
