BD, 559920, PE Rat Anti-Mouse CD131 JORO50 (also known as JORO 50)

The JORO50 monoclonal antibody specifically recognizes the extracellular regions of the mouse CD131/βc (Bc, AIC2B, Il3rb1, Csf2rb1) and βIL3 (BIL3, AIC2A, Il3rb2, Csf2rb2) cytokine receptor subunits. A variety of mouse cell types, including multipotential hematopoietic stem cells, mast cells, megakaryocytes, eosinophils, erythroblasts, pre-B cells, and osteoclasts, express βIL-3 and βc subunits. Either βIL-3 or βc can combine with the IL-3Rα chain to form two distinct, functional (i.e., signaling), high affinity receptors for mouse IL-3. The βIL-3 subunit by itself can bind mouse IL-3 with low affinity whereas the βc subunit can not. βc (but not βIL-3) can combine with the IL-5Rα (CD125) and GM-CSFRα (CD116) subunits to form high affinity, signaling receptors for mouse IL-5 or GM-CSF, respectively. The immunogen used to generate the JORO50 hybridoma was the bone marrow-derived, C4-77 pro-T lymphocyte clone.

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.
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.
