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.
DESCRIPTION
IL6R produced in Sf9 Insect cells is a single, glycosylated polypeptide chain containing 603 amino acids (23-617a.a.) and having a molecular mass of 67.7kDa (Molecular size on SDS-PAGE will appear at approximately 70-100kDa).
IL6R is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
SOURCE
Sf9, Insect cells.
PHYSICAL APPEARANCE
Sterile filtered colorless solution.
FORMULATION
IL6R protein solution (1mg/ml) contains phosphate buffered saline (pH7.4) and 10% glycerol.
STABILITY
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
