Human IL-31 RA Protein
Recombinant Human IL-31 RA Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ala20-Glu519 [Accession | Q8NI17-1].
The protein has a predicted MW of 58.2 kDa. Due to glycosylation, the protein migrates to 80-110 kDa based on Bis-Tris PAGE result.
>95% as determined by Bis-Tris PAGE
>90% as determined by HPLC
Less than 1 EU per μg by the LAL method.
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human IL-31 RA on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Human IL-31 RA is greater than 90% as determined by SEC-HPLC.
Immobilized Human IL-31 RA, His Tag at 1 μg/ml (100 μl/well) on the plate. Dose response curve for Anti-IL-31 RA Antibody, hFc Tag with the EC50 of 4.7 ng/ml determined by ELISA (QC Test).
Human IL-31, His Tag immobilized on CM5 Chip can bind Human IL-31 RA, His Tag with an affinity constant of 125.61 nM as determined in SPR assay (Biacore T200).
Interleukin-31 receptor A (IL-31RA) is a newly identified type I cytokine receptor, that is related to gp130, the common receptor of the interleukin (IL) -6 family cytokines. IL-31RA forms a functional receptor complex for IL-31 together with the beta subunit of oncostatin M receptor (OSMR beta). OSMR beta is expressed in a subset of small-sized nociceptive neurons of adult dorsal root ganglia (DRGs). IL-31 and OSM may thus have redundant functions in the development of OSMRbeta-expressing neurons.
