IL-6 Human Recombinant Protein Description


Cytokines of the IL6/GCSF/MGF family are glycoproteins of about 170 to 180 amino acid residues that contains four conserved cysteine residues involved in two disulfide bonds. They have a compact, globular fold (similar to other interleukins), stabilized by the 2 disulfide bonds. One half of the structure is dominated by a 4 alpha-helix bundle with a left-handed twist: the helices are anti-parallel, with 2 overhand connections, which fall into a 2-stranded anti-parallel beta-sheet. The fourth alpha-helix is important to the biological activity of the molecule. Interleukin (IL)-6 is an important proinflammatory and immunoregulatory cytokine expressed by various cells. Interleukin-6 has been shown to inhibit the growth of early stage and to promote the proliferation of advanced stage melanoma cells in vitro. Recombinant Human IL-6 produced in E.coli is a single, non-glycosylated polypeptide chain containing 184 amino acids and having a molecular mass of 21,000 Daltons.

Storage Condition

Store vial at 4 °C prior to restoration. Dilute only prior to immediate use. Maintain sterility. This product DOES NOT contain preservative. DO NOT VORTEX. We recommend adding a carrier protein such as HSA or BSA to 0.1% (i.e. 1.0 mg/mL) . For best results aliquot contents and freeze at -20 °C or colder. Avoid cycles of freezing and thawing. Centrifuge vial before each opening to dislodge contents from the cap and to clarify if contents are not clear after standing at room temperature.

Application Note

This product is lyophilized from a 10 mM acetic acid solution. For easiest restoration, it is recommended to restore with 200 µl of 10 mM HCL for a stock concentration of 0.1 mg/ml. This solution can be further diluted in deionized water or other buffers as required. Interleukin-6 (IL-6) is suitable as a control for polyclonal or monoclonal anti-Interleukin-6 (IL-6) in immunological assays.


Purity greater than 95% as determined by analysis of RP-HPLC and reducing and non-reducing SDS-PAGE against a known standard.
