|Synonyms||Interleukin-6; B Cell Stimulatory Factor 2; BSF-2; CTL Differentiation Factor; CDF; Interferon β2; IFN-β2|
|Sequence||The extracellular domain of human IL-6 (aa 30-212) is fused to the N-terminus of the Fc region of a mutant human IgG1.|
|Biological Activity||Shows the biological function of the IL-6 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain.|
|Endotoxin Content||<0.06EU/μg protein (LAL test; Lonza).|
|Reconstitution||Reconstitute at 100μg/ml in sterile PBS.|
|Formulation||Lyophilized from 0.2μm-filtered solution in PBS.|
|Other Product Data||Non-lytic: Acts as a long lasting fusion protein which only binds to the receptor. Mutations to the complement (C1q) and FcgR I binding sites of the IgGs Fc fragment render the fusion proteins incapable of antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC).

Interleukin 6 (IL-6) is a pleiotropic α-helical cytokine that plays important roles in acute phase reactions, inflammation, hematopoiesis, bone metabolism and cancer progression. IL-6 activity is essential for the transition from acute inflammation to either acquired immunity or chronic inflammatory disease. It is secreted by multiple cell types as a 22kDa-28kDa phosphorylated and variably glycosylated molecule. IL-6 induces signaling through a cell surface heterodimeric receptor complex composed of a ligand binding subunit (IL-6R) and a signal transducing subunit (gp130). IL-6 is a key factor for the growth of plasma cells.
