Interleukin-6 (IL-6) is an interleukin that acts as both a pro-inflammatory cytokine and an anti-inflammatory myokine. In humans, it is encoded by the IL6 gene. In addition, osteoblasts secrete IL-6 to stimulate osteoclast formation. Smooth muscle cells in the tunica media of many blood vessels also produce IL-6 as a pro-inflammatory cytokine. IL-6’s role as an anti-inflammatory myokine is mediated through its inhibitory effects on TNF-alpha and IL-1, and activation of IL-1RA and IL-10.

with polyhistidine tag at the C-terminus

Escherichia coli
Animal-free reagent and laboratory
Manufactured and tested under GMP guideline

Endotoxin level:
<0.1 EU per 1 μg of the protein by the LAL method. Activity:
Measure by its ability to induce proliferation in TF-1 cells The ED50 for this effect is <0.5 ng/mL. The specific activity of recombinant human IL-6 is approximately >5 x 108 IU/mg.
Measure by its ability to induce proliferation in MCF-7 cells. The ED50 for this effect is <4.4 ng/mL. Purity:
>98% as determined by SDS-PAGE. Purified by Ni-NTA chromatography.

The protein was lyophilized from a solution containing 1X PBS, pH 8.0.

It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

Lyophilized protein should be stored at -20°C. This product is stable for one year upon receipt, when handled and stored as instructed. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C. Avoid repeated freeze/thaw cycles.

Please use within one month after protein reconstitution.
