Multicolor flow cytometric analysis of IL-33R (ST2) expression by mouse splenocytes. BALB/c mouse splenic leucocytes were stained with BD Horizon™ Fixable Viability Stain 510 (Cat. No. 564406) followed by staining with Alexa Fluor® 488 Rat Anti-Mouse CD4 antibody (Cat. No. 557667) and either PE Rat IgG2a, κ Isotype Control (Cat. No. 553930; Left Plot) or PE Rat Anti-Mouse IL-33R (ST2) antibody (Cat. No. 566311/566312; Right Plot). The cells were then fixed and permeabilized using the BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574/562725) and stained with Alexa Fluor® 647 Rat Anti-Mouse Foxp3 (Cat. No. 560401/560402). Two-color flow cytometric contour plots showing the correlated expression of Foxp3 versus IL-33R (ST2) [or Ig Isotype control staining] were derived from CD4-positive gated events with the forward and side light-scatter characteristics of live cell-discriminated intact lymphocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System.

- 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 U29-93 monoclonal antibody specifically binds to the mouse Interleukin-33 Receptor (IL-33 Receptor, or IL-33R) which is also known as ST2. The IL-33R exists in either a type I transmembrane or soluble glycoprotein form. These IL-33R forms are encoded by the Il1rl1 (Interleukin-1 receptor-like 1) gene which belongs to the IL-1 Receptor family within the Ig superfamily. The IL-33R is expressed by subsets of T cells, including Th2-like cells and some regulatory T cells, as well as some innate lymphocytes, eosinophils, basophils, and mast cells. The IL-33R (also known as the IL-33R alpha subunit, or IL-33Rα) binds IL-33 and complexes with the IL-1R Accessory Protein (IL1RAP) to form a functional signaling receptor complex that can induce the production of T helper type 2 (Th2) cytokines. The soluble IL-33R may function as a decoy receptor which can block the binding of IL-33 to the transmembrane IL-33R. The IL-33R plays roles in inflammation, immunity, and allergy.
