Recombinant Human IL20RB /IL-20R2 Protein, With C-Fc Tag (rhIL20RB Fc Chimera) Asp 30 - Ala 230 (Accession # AAH63696) was produced in human 293 cells (HEK293) at ACRObiosystems.

Molecular Characterization

rhIL20RB Fc Chimera, 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.


Less than 1.0 EU per μg of the rhIL20RB Fc Chimera by the LAL method.


>90% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in 50 mM tris, 100 mM glycine, pH7.0. Normally Mannitol or Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for details of reconstitution instruction and specific concentration.


Avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:
In lyophilized state for 1 year (4oC); After reconstitution under sterile conditions for 3 months (-70oC).



Recombinant Human IL20RB /IL-20R2 Protein, With C-Fc Tag
The purity of rhIL20RB Fc Chimerawas determined by DTT-reduced (+) and non-reduced (-) SDS-PAGE and staining overnight with Coomassie Blue.


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.
