Recombinant Human IL-6
DescriptionInterleukin-6 (IL-6) is a cytokine that is expressed by T cells, macrophages, and muscle cells. IL-6 acts to stimulate an immune response upon infection or trauma. IL-6 has both pro-inflammatory and anti-inflammatory functions and signals through the cell-surface type 1 cytokine receptor complex containing the IL-6Ra and gp130 chains. Human IL-6 is active on mouse and rat cells.
Activity AssayHuman IL-6 is fully biologically active when compared to standard. The activity is determined by the ability to induce 7TD1 cells proliferation and it is typically less than 250 pg/ml. This corresponds to an expected specific activity of 4 x 106 units/mg.

|Molecular Weight||21 kDa|
|Purity||≥95% determined by reducing and non-reducing SDS-PAGE|
|Endotoxin Level||≤1.00 EU/μg as measured by kinetic LAL|
|Formulation||Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 0.1% Trifluoroacetic Acid (TFA)|
|Reconstitution||Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile 10 mM HCI at 0.1 mg/ml, which can be further diluted into other aqueous solutions.|
|Stability and Storage||
12 months from date of receipt when stored at -20°C to -80°C as supplied. 1 month when stored at 4°C after reconstituting as directed. 3 months when stored at -20°C to -80°C after reconstituting as directed.
