IL6R-alpha, CD126, IL-6R 1, CD126 antigen, IL6RA, Interleukin 6 receptor, Interleukin 6 receptor alpha subunit, Interleukin-6 receptor alpha chain precursor, B cell stimulatory factor-2, Membrane glycoprotein 80, gp80, IL-6R, MGC104991.
The IL-6 receptor complex is composed of two membrane glycoproteins: the low affinity receptor and the signaltransducing component. The soluble form of IL6R is found in the urine of healthy adult humans and the serum of HIV positive individuals, as well as in the cell culture supernatants of stimulated PBMC’s. This soluble form of IL6R results from either proteolytic cleavage from the membrane, or an isoform derived splice variant.
sIL6R produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (20-365 a.a.) and fused to a 9 aa His Tag at C-terminus containing a total of 355 amino acids and having a molecular mass of 39.6kDa.
sIL6R shows multiple bands between 40-57kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques.
sIL6R protein solution (0.25mg/ml) contains 10% glycerol & Phosphate buffered saline (pH7.4).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
Safety Data Sheet
Measured by its ability to inhibit proliferation using M1 mouse myeloid leukemia cells. The ED50 range ≤ 20 ng/ml with Human IL-6.
