Human IL-6

Human IL-6

IL-6 stands for interleukin 6. Human IL-6 is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.


Human IL-6 can be used for a variety of applications, including:
  • Induction of colony formation from hematopoietic progenitor cells in semi-solid medium.
  • Replacement of feeder cells in the preparation of murine and human hybridomas.
  • In vitro differentiation of TH 17 cells.

Background information

IL-6, originally identified as a B cell differentiation factor, is a multifunctional cytokine, which regulates immune responses, hematopoiesis, acute phase responses, and inflammatory reactions. It induces, for instance, the terminal maturation of activated B cells into antibody-secreting plasma cells and acts in synergy with IL-3 to support the proliferation of hematopoietic stem cells. IL-6 is produced by many cell types, such as monocytes, fibroblasts, endothelial cells, T cells, etc. Disturbed IL-6 production has been associated with pathological processes including inflammatory autoimmune diseases, such as rheumatoid arthritis and cancer.

Quality description

cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.
cytokines offer the convenience of high and well-defined biological activities and allow exact unit dosing for demanding applications. The biological activity is determined after lyophilization and reconstitution, and normalized to WHO/NIBSC standards whenever available. In general, endotoxin levels are <0.01 ng/μg (<0.1 EU/μg), and purities are >97%. Lot-specific certificates of analysis are available on request (
