PE Rat Anti-Mouse IL-33R (ST2)
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.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.

U29-93

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.

PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
