Two-color flow cytometric analysis of CCR9 expression on mouse thymocytes and splenocytes. C57BL/6 mouse thymocytes (Top Plots) and splenic leucocytes (Bottom Plots) were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with APC Rat Anti-Mouse CD8a antibody (Cat No. 553035/561093), and either PE Mouse IgG2a Isotype Control (Cat. No. 553457; Left Plots) or PE Mouse Anti-Mouse CD199 (CCR9) (Cat. No. 565576; Right Plots) at 0.5 µg/test. Two-color flow cytometric contour plots showing the correlated expression of CD199 (CCR9) [or Ig Isotype control staining] versus CD8a were derived from gated events with the forward and side light-scatter characteristics of viable cells. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System. Data shown on this Technical Data Sheet are not lot specific.

- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- 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.

The CW-1.2 monoclonal antibody specifically binds to CD199 which is also known as Chemokine (C-C motif) receptor 9 (CCR9) or C-C chemokine receptor type 9 (C-C CKR-9). CD199 is a ~42 kDa seven-transmembrane protein and member of the G protein-coupled receptor 1 family. CD199 binds to CCL25, which is likewise known as thymus-expressed chemokine (TECK) or small inducible chemokine 25 (Scya25). CCL25 is selectively and constitutively expressed in the thymic cortex and small intestinal epithelium. CD199 is highly expressed on CD4+CD8+ double-positive thymocytes, and mature naïve CD8+ T cells, but not naïve CD4+ T cells, in the peripheral lymphoid organs. CD199 is also expressed on small intestinal B cells, and on subsets of memory CD4+ T cells and CD8+ T cells, and dendritic cells. The CCR9/CCL25 pathway plays important roles in T cell development and gut-associated immune functions. It is especially involved in the recruitment of CD8αα+ intraepithelial lymphocytes (IELs) and the homing of other lymphocytes to the gut. Dysregulation of this pathway is associated with inflammatory responses, such as inflammatory bowel disease (IBD) and celiac disease.
