Scientific Background
Interleukin-20 receptor subunit beta(IL20RB) is a single-pass type I membrane protein and belongs to the type II cytokine receptor family. It contains 2 fibronectin type-III domains. There are two kinds of type II cytokine receptors : cytokine receptors that bind type I and type II interferons; cytokine receptors that bind members of the interleukin-10 family (interleukin-10, interleukin-20 and interleukin-22). Type II cytokine receptors are similar to type I cytokine receptors except they do not possess the signature sequence WSXWS that is characteristic of type I receptors. They are expressed on the surface of certain cells, which bind and respond to a select group of cytokines.

Safety & Handling
Research use only
This protein was produced in Mammalian (HEK293). Mammalian expression enables human-like glycosylation, correct disulfide bond formation, and proper protein folding — all critical for proteins used in binding interaction studies (SPR/BLI) and antibody characterisation. For transmembrane proteins expressed as ectodomains or nanodisc preparations, the expression system directly affects binding conformation and assay performance.
The expressed amino acid region is specified in the protein specifications table. Cross-reference with the UniProt entry (Q6UXL0) to confirm the expressed region includes your domain of interest — receptor-binding domain, extracellular domain, or specific epitope — before ordering.
Greater than 85% as determined by reducing SDS-PAGE.. A gel image showing the protein band is provided with each lot on the Certificate of Analysis. This high-purity specification is suitable for SPR/BLI kinetics measurements, ELISA standard curve development, and antibody epitope binding studies.
Please refer to the Certificate of Analysis (CoA) for reconstitution instructions for your specific lot. Storage: Store at ≤-70°C, stable for 6 months after receipt. Store at ≤-70°C, stable for 3 months under sterile conditions after opening. Please minimize freez Prepare single-use working aliquots after reconstitution to avoid repeated freeze-thaw cycles. Lyophilized protein is stable for 12 months at −80°C from the date of receipt.
