IL5, Human

GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!Recombinant Human Interleukin 5Colony-Stimulating Factor, eosinophilEosinophil Differentiation Factor, EDFT-cell Replacing Factor, TRFTheIL5gene is located on chromosome 5 in humans, in close proximity to the genes encoding IL3, IL4, and granulocyte-macrophage colony-stimulating factor (CSF2), which are often co-expressed in TH2 cells. Through binding to the IL5 receptor, IL5 stimulates B cell growth and increases immunoglobulin secretion and is also a key mediator in eosinophil activation. Interleukin 5 has long been associated with the cause of several allergic diseases including allergic rhinitis and asthma. Human IL5 is 115 amino acids long (murine IL5 has 133 amino acids) and is a TH2 cytokine that is part of the hematopoietic family. Unlike other members of this cytokine family (namely IL3 and CSF2), this glycoprotein is a homodimer in its active form.Sterile Filtered White lyophilized powder.
