蛋白结构(Molecular Characterization)

IL-31 RA Structure

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 83.5 kDa. The protein migrates as 105-115 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

电泳(SDS-PAGE)

IL-31 RA SDS-PAGE

Human IL-31 RA, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

 

活性(Bioactivity)-ELISA

IL-31 RA ELISA

Immobilized Human IL-31, His Tag (Cat. No. IL1-H5247) at 1 μg/mL (100 μL/well) can bind Human IL-31 RA, Fc Tag (Cat. No. ILA-H5256) with a linear range of 0.01-0.313 μg/mL (QC tested).

Protocol

 

活性(Bioactivity)-SPR

IL-31 RA SPR

Human IL-31, His Tag (Cat. No. IL1-H5247) capture on NTA-Series S sensor chip can bind Human IL-31 RA, Fc Tag (Cat. No. ILA-H5256) with an affinity constant of 37.1 nM as determined in a SPR assay (Biacore 8K) (Routinely tested).

Protocol

 

背景(Background)

Interleukin-31 receptor subunit alpha is a protein that in humans is encoded by the IL31RA gene, also known as IL-31 receptor subunit alpha, IL-31RA, GLM-R, Gp130-like receptor, CRL3, GPL. Oncostatin M receptor (OSMR) and IL31RA form the heterodimeric receptor through which IL31 signals. IL31RA is a strong activator of STAT3 and STAT5, whereas STAT1 is only marginally tyrosine-phosphorylated. dditionally, demonstrate Jak1 binding to GPL and its activation in heteromeric complexes with the OSMRbeta but also in a homomeric receptor complex.
