NovActive recombinant human IL-6 is produced in the endosperm tissue of barley grain (Hordeum vulgare), that exhibits up to 50 times less protease activity than E.coli or mammalian cells. Barley seed is void of any human or animal viral contaminants that could jeopardize your cell culture.
Note: Not all species have been tested for usefulness with this product. Only those species listed have been tested. We cannot make any guarantees about additional reactivities which may or may not occur.
Recombinant human IL-6 contains 185 amino acids and a 16 a.a. Histidine-based tag for a total length of 201 a.a. and has a predicted molecular mass of 23.1 kDa. As a result of glycosylation, the recombinant protein migrates with an apparent molecular mass of 23-24 kDa in SDS-PAGE.

IL-6 is a multifunctional cytokine that has an important role in host defense by regulating immune and inflammatory responses. It is expressed by a variety of normal and transformed cells including T cells, B cells, monocytes/macrophages, fibroblasts and various tumor cells. IL-6 has diverse biological functions, it stimulates B-cell differentiation and antibody production, synergizes with IL-3 in megakaryocyte development and platelet production, induces expression of hepatic acute-phase proteins, and regulates bone metabolism. Recombinant human IL-6 is a 20.9 kDa protein containing 184 amino acid residues. Human IL-6 is active on murine cells but murine IL-6 is inactive on human cells.
Functional Assay: IL-6 Protein [NBC1-21346] - The ED50 for this batch of NovActive recombinant human IL-6 is 0.20 ng/ml, corresponding to 5.0 x 106 U/mg specific activity.
