Recombinant mouse IL-17RB binds to immobilized recombinant mouse IL-17E at 0.5 µg/mL (Cat. No. 587302) in a dose dependent manner. The ED50 for this effect is 3 - 15 ng/mL. -
Stability Testing for Recombinant Mouse IL-17RB. Recombinant Mouse IL-17RB was aliquoted in PBS, pH 7 at 0.2 mg/mL. One aliquot was frozen and thawed four times (4x Freeze/Thaws) and compared to the control that was kept at 4⁰C (control). The samples were tested for their ability to bind to recombinant mouse IL-17E in a dose dependent manner. The ED50 for this effect is 3 - 15 ng/mL.

IL-17RB belongs to the family of IL-17 receptors that includes IL-17RA to IL-17RE. The IL-17 receptors are single transmembrane proteins and contain in the extracellular portion fibronectin type-III domains. In the intracellular portion, the IL-17 receptors have a unique structural motif called SEFIR [SEF (similar expression to fibroblast growth factor genes) and IL-17R] domain. The IL-17 family members are six ligands including IL-17A to IL-17F. IL-17B and IL-17E bind to IL-17RB with different affinities, thus IL-17E binds to IL-17RB with higher affinity than IL-17B. The binding of IL-17B to the homodimeric receptor IL-17RB induces pro-inflammatory cytokines TNF-α, IL-1β, IL-6, CXCL8/IL-8, and migration in neutrophils to the peritoneal cavity in rats. Multiple isoforms of IL-17RB have been detected in both human and mouse. These isoforms include soluble receptors derived by intron incorporation or by proteolytic cleavage. High levels of IL-17B and soluble lL-17RB have been detected in the plasma of patients with alveolar Echinococcosis (AE). Overexpression of IL-17RB is associated with murine leukemia cells. In humans, upregulation in signal transduction of IL-17B/IL-17RB promotes breast cancer tumorigenicity, and high expression of IL-17RB correlates with worse prognosis in pancreatic cancer patients.

Expressed on iNKT cells, innate lymphoid cells (ILC), Th2, Th9, mesenchymal stem cells, cancer cells.
- Function
- Critical role in Th2-type immune response. The interaction IL-17E/IL-17RB induces IL-8 pro-inflammatory cytokine. The interaction IL-17RB/IL-17B promotes breast tumorigenicity, induces chemokines: CCL20, CXCL1, IL-8, and TFF1 in pancreatic cancer cells and cancer cell invasion. Also, promotes growth and migration of gastric tumor cells.
- Interaction
- Interacts with IL-17RA to form a heterodimeric receptor complex involved in IL-25 signaling.

• Learn more about our Recombinant Proteins. - How does the activity of your recombinant proteins compare to competitors?
-
We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!
- What is the specific activity or ED50 of my recombinant protein?
-
The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.
- Have your recombinants been tested for stability?
-
Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.
- Does specific activity of a recombinant protein vary between lots?
-
Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.
- How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
-
Use formula Specific activity (Units/mg) = 10^6/ ED50 (ng/mL)
