Product Description	Recombinant Biotinylated Human IL-4 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus; It contains His25-Ser153.
Product Background	Interleukin-4, also known as IL4, is a secreted protein which belongs to the IL-4/IL-13 family. Interleukin-4/IL4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation. In the presence of IL-4 and IL-13, cytokines that are produced in a Th-2 type response, particularly during allergy and parasitic infections, macrophages become differentially activated, And this cytokine is a ligand for interleukin 4 receptor.
