Binding Capacity: N/A

Unit Definition: N/A

Molecular Weight: This protein fused with Fc fragment of human IgG1 at the C-terminus, has a calculated MW of 49.1 kDa. The predicted N-terminus is Asp 30. As a result of glycosylation, DTT-reduced Protein migrates as 50 kDa and non-reduced protein migrates as 100 kDa.

Concentration: N/A

Appearance: Lyophilized

Physical form description: Lyophilized from 0.22 μm filtered solution in 50 mM tris, 100 mM glycine, pH 7.0. Normally Mannitol or Trehalose is added as protectants before lyophilization.

Reconstitution Instructions: Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.

Background Information: Interleukin-20 receptor subunit beta (IL20RB) is also known as IL-20R2, DIRS1, which belongs to the type II cytokine receptor family. IL20RB / IL-20R2 contains two fibronectin type-III domains. IL20RB / IL-20R2 is widely expressed with highest levels in skin and testis. IL20RB can be fused with IL20RA or IL22RA1 forming heterodimer. The IL20RA/IL20RB dimer is a receptor for IL19, IL20 and IL24. The IL22RA1/IL20RB dimer is a receptor for IL20 and IL24.

Amino acid sequence: N/A

Handling: Centrifuge the vial prior to opening.

Usage: For Research Use Only! Not to be used in humans
