Description

IL-6 is a multifunctional cytokine that can regulate various immune and inflammatory responses. Several studies have suggested a crucial role for IL-6 in angiogenesis. The use of mice deficient in IL-6 (-/-) demonstrated a critical role for this protein in a mouse model of lung angiogenesis. IL-6 has been shown to cause proliferation and migration of systemic endothelial cells in culture (1). The classical responsiveness to IL-6 is governed by a receptor complex consisting of two membrane-bound subunits, an 80-kD cognate chain (IL-6R), and a ubiquitously expressed 130-kD β-chain receptor (gp130) which acts as the universal signal-transducing element for all IL-6 family cytokines (2). Alternatively, IL-6 regulation of leukocyte trafficking relies upon signaling via its soluble IL-6R (termed IL-6 trans-signaling) (3). IL-6 plays a major role in regulating neutrophil clearance during acute peritoneal inflammation; as a result of specific down-regulation of neutrophil-attracting chemokine (CXCL1/KC) production (4). IL-6 is a key factor that reciprocally regulates Th17 and Foxp3(+) Treg differentiation by inhibition of TGF-beta induced Foxp3 and induction of RORɣt, a Th17 lineage-specific transcription factor (5).

Product Details

Source
Human IL-6, amino acids Pro29-Met212 (Accession # NM_000600) was expressed in E. coli.
Molecular Mass
The 185 amino acid N-terminal methionylated recombinant protein has a predicted molecular mass of 21 kD. The DTT-reduced and non-reduced protein migrate at approximately 23 kD by SDS-PAGE.
Purity
> 95%, as determined by Coomassie stained SDS-PAGE
Formulation
0.1 µm filtered protein solution is in 10 mM NaH2PO4, 150 mM NaCl, pH 7.2.
Endotoxin Level
Less than 0.1 EU per µg protein as determined by the LAL method
Concentration
500 µg/mL
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
Activity
ED50 = 4 - 20 pg/mL, as determined by a dose-dependent stimulation in a 7TD1 cell proliferation assay. The specific activity of GMP recombinant human IL-6 is approximately 5.0 x 104 IU/µg when compared against the WHO Reference Reagent for Human IL-6 (NIBSC code: 89/548) as determined by the dose-dependent stimulation of 7TD1 cell proliferation.
