Brand: BD Pharmingen™

Characteristics: The mIL4R-M1 monoclonal antibody specifically binds to CD124 which is also known as the α subunit of the mouse Interleukin-4 Receptor (IL-4Rα). The mouse IL-4Rα is a 140 kDa transmembrane glycoprotein that is expressed by B and T lymphocytes and a variety of other hematopoietic and nonhematopoietic cells and cell lines. The cell surface IL-4Rα chain binds IL-4 with high affinity and associates with either the common γ chain (IL-4Rα/γc, aka, type I IL-4R) or the IL-13 receptor alpha subunit (IL-4Rα/IL-13Rα, aka, type II IL-4R complex) to form two distinct types of signal-transducing IL-4R complexes. The type I IL-4 receptor complex specifically binds IL-4 whereas the type II IL-4R binds and transduces signals from either IL-4 or IL-13. The mIL4R-M1 antibody blocks IL-4 binding to cells and is reported to be a potent inhibitor of IL-4's biological activities. The mIL4R-M1 antibody also recognizes naturally-occurring, soluble truncated forms of IL-4Rα (sIL-4R) that result either from enzymatic cleavage of the cell surface extracellular IL-4Rα domain or from differential mRNAsplicing and secretion by cells. These sIL-4R retain their high-affinity ligand binding domain and appear to either enhance or inhibit IL-4-mediated functions depending on the relative local levels of IL-4 and sIL-4R. Expression of cell surface CD124 by B220-positve and -negative splenic lymphocytes from C57BL/6 mice. Spleen cells from C57BL/6 mice were treated with ACK lysis buffer, washed, and were labeled with purified mouse BD Fc Block™ (Cat. No. 553142) to block mouse Fc receptors. The cells were then stained with biotinylated mIL4R-M1 (0.125 μg/10^6 cells) followed by streptavidin phycoerythrin (0.015 μg, Cat. No. 554061) and FITC anti-mouse B220 (0.06 μg, Cat. No. 553088) and were analyzed by two-color flow cytometry. The levels of CD124 expressed by B220-positive and B220-negative cells (with the light-scattering characteristics of viable lymphocytes) are shown in the two-color dot plot (right panel). Staining with the biotinylated mIL4R-M1 antibody (right panel) is compared to staining derived with a biotinylated rat IgG2a immunoglobulin isotype control antibody (0.125 μg, Cat. No. 553928) that is shown in the left panel.
