Alternate Names:  IFN-β2, B-cell Differentiation Factor, BSF-2, HSF, MGI-2              

Accession Number: P05231
Description:  Interleukin 6 (IL-6) is an important pro-inflammatory and anti-inflammatory cytokine expressed by T cells, macrophages and muscle cells. IL-6 signals through a receptor complex containing two receptors, IL-6Rα and gp130. IL-6 has an important function in promoting fever and can serve to stimulate an immune response to trauma. IL-6 is often used for growth of hybridoma cell lines. Human IL-6 is active on mouse and rat cells.
Source:  Genetically modified E.coli.
Predicted MW: Monomer, 21 kDa (185 aa)
Formulation:  Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 10 mM sodium phosphate, pH 7.5
