Source
Human OSMR, His Tag (OSR-H52H9) is expressed from human 293 cells (HEK293). It contains AA Glu 28 - Met 740 (Accession # Q99650-1).
Predicted N-terminus: Glu 28
Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 83.0 kDa. The protein migrates as 105-125 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background
Oncostatin-M-specific receptor subunit beta(OSMRB) alos know as Interleukin-31 receptor subunit beta (IL-31RB), is an alternative subunit (OSMRβ) for an OSM receptor complex (a heterodimer of gp130 and OSMRβ), that is activated by OSM but not by LIF. OSMR beta associates with the low affinity OSM·gp130 complex to form a high affinity heterodimeric receptor that is capable of transducing OSM-specific signaling events.
