Flow cytometric analysis of IL-17RA (CD217) expression on peripheral blood leucocytes. Whole blood was stained with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Left Plot) or PE Mouse Anti-Human CD217 (IL-17RA) (Cat. No. 566736; Right Plot) at 0.5 μg/test. Samples were then treated with 1× BD Pharm Lyse™ lysing solution (Cat. No. 555899) to remove erythrocytes. The contour plots showing IL-17RA (CD217) [or Ig isotype control] staining versus side light-scatter were derived from gated events with the forward and side light-scatter characteristics of viable leucocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- When excited by the yellow-green (561-nm) laser, the fluorescence may be brighter than when excited by the blue (488-nm) laser.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

The W23-251 monoclonal antibody specifically recognizes IL-17RA (CD217), which is also known as Interleukin-17 receptor A. IL-17RA (CD217) is a ~120 kDa single-pass type I transmembrane glycoprotein that is encoded by IL17RA. IL-17RA (CD217) belongs to the IL-17 receptor family which also includes IL-17 RB, IL-17RC, IL-17RD, and IL-17RE. IL-17RA (CD217) has a wide tissue distribution and is variably expressed on granulocytes, monocytes, macrophages, dendritic cells (DCs), T cells, B cells, NK cells, smooth muscle cells, endothelial cells, and epithelial cells. Interleukin-17A (IL-17A) or IL-17F homodimers, or IL-17A:IL-17F heterodimers can bind to and signal through functional IL-17 receptor complexes comprised of IL-17RA (CD217) and IL-17RC subunits. This leads to the cellular release of proinflammatory cytokines including IL-1, IL-6, and TNF, antimicrobial peptides, and chemokines that attract neutrophils. IL-17E/IL-25 binds to and signals through another functional IL-17 receptor complex comprised of IL-17RA (CD217) and IL-17RB subunits. IL-17E/IL-25 induces type-2 (Th2-like) immune responses and is implicated in asthma. IL-17C binds to IL-17 receptor complexes comprised of IL-17RA (CD217) and IL-17RE subunits and can stimulate the production of proinflammatory cytokines and antimicrobial peptides.
