Product Description	Recombinant Cynomolgus IL-4 Protein is expressed from HEK293 with His 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.-.
Product Category	Recombinant Protein / Antibody discovery
