Mature mouse IL-6 was expressed in Pichia pastoris, X-33. GenBank Accession # NP_112445, amino acids 25 – 211. For protein verification, the expressed protein was N-terminal sequenced and begins with the following 10 amino acids: FPTSQVRRGD. Purity is >95% by SDS-PAGE analyses.
Use: For in vitro applications. A dose-response assay should be performed to determine the optimal concentration for specific experiments.
Reconstitution and Dilution: Store lyophilized material at 4°C. Reconstitute in 0.5 mL of distilled or deionized water. Dilute in a buffer-containing carrier protein, aliquot, and store at or below -70°C, avoiding multiple freeze-thaw cycles. PBS with 1% BSA or a neutral media containing <10% FCS are suitable buffers.
Interleukin 6 (IL-6) is a multifunctional 26 kD protein originally discovered in the medium of RNA-stimulated fibroblastoid cells. IL-6 appears to be directly involved in the responses that occur after infection and cellular injury, and it may prove to be important as IL-1 and TNF-a in regulating the acute phase response. IL-6 is reported to be produced by fibroblasts, activated T cells, activated monocytes or macrophages and endothelial cells. IL-6 acts upon a variety of cells including myeloid progenitor cells, T cells, B cells, and hepatocytes. In addition, IL-6 appears to interact with IL-2 in the proliferation of T lymphocytes. IL-6 potentiates the proliferative effect of IL-3 on multipotential hematopoietic progenitors. IL-6 plays a critical role in B-cell differentiation to plasma cells and is a potent growth factor for plasmacytoma and myeloma. IL-6 is a very useful culture supplement for the generation of a high number of antibody-producing hybridomas. Primarily produced at sites of acute and chronic inflammation, IL-6 is secreted into the serum and induces a transcriptional inflammatory response through interleukin 6 receptor, alpha. The functioning of IL-6 is implicated in a wide variety of inflammation-associated disease states including diabetes mellitus and systemic juvenile rheumatoid arthritis.
