| Description | Recombinant Human Interleukin-6 is produced by our E.coli expression system and the target gene encoding Pro29-Met212 is expressed. |
| Names | Interleukin-6, IL-6, B-Cell Stimulatory Factor 2, BSF-2, CTL Differentiation Factor, CDF, Hybridoma Growth Factor, Interferon Beta-2, IFN-Beta-2, IL6, IFNB2 |
| Accession # | P05231 |
| Formulation | Lyophilized from a 0.2 μm filtered solution of 20mM HAc-NaAc, 150mM NaCl, pH 5.0. |
| Shipping | The product is shipped at ambient temperature. |
| Reconstitution | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| Storage | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
| Biological Activity | ED50 is less than 0.1 ng/ml. Specific Activity of 5.0 x 10^7 IU/mg. |
| Purity | Greater than 95% as determined by reducing SDS-PAGE. |
| Endotoxin | Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test. |

| Background | Cytokines of the IL6/GCSF/MGF family are glycoproteins of about 170 to 180 amino acid residues that contain 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-6 (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. |
