Alternative Names

IL-31RB,OSMR,IL-31R-beta,IL-31R subunit beta

Species

Human

Expression Sequence

Glu28-Met740

Accession

Q99650-1

Tag

C-hFc

Expression System

HEK293

Molecular Weight

The protein has a predicted MW of 107.06 kDa. Due to glycosylation, the protein migrates to 120-140 kDa based on SDS-PAGE result.

Purity

> 95% as determined by SDS-PAGE and HPLC.

Endotoxin

< 1.0 EU per μg by the LAL method.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Appearance

Lyophilized Powder

Biological Activity

【ELISA Data】 Immobilized Human OSMR, hFc Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Anti-OSMR Antibody, hFc Tag with the EC50 of 4.0ng/ml determined by ELISA.

Reconstitution Method

Before opening, centrifuge briefly. Reconstitute the lyophilized protein with distilled water to a concentration exceeding 100 μg/mL. Aliquot after initial reconstitution to avoid repeated freeze-thaw cycles.
