- Description
| Specificity Profile | More Information |
 | The specificity of IL3RA Monoclonal Antibody (CSB0004) was tested on the Membrane Proteome Array™ and shown to be specific for human IL3RA. The Membrane Proteome Array™ contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array™ represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |
| Application | Conditions | Recommended Concentration |
| Flow Cytometry, Extracellular | Live, Unpermeabilized | 1 µg/ml |
 | HEK-293F cells transiently transfected with human IL3RA were stained with IL3RA Monoclonal Antibody (CSB0004) (green) or isotype control antibody (gray), followed by AlexaFluor 647-conjugated anti-Mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with IL3RA Monoclonal Antibody (CSB0004) (blue). | |

IL3RA is a single-pass transmembrane protein and the alpha subunit of a heterodimeric cytokine receptor. IL3RA binds interleukin 3, which activates the signal transducing beta subunit, activating the pathway responsible for regulating concentrations of various blood cell types. The beta subunit is shared with receptors for colony stimulating factor 2 and interleukin 5. (NCBI Gene: 3563, UniProtKB/Swiss-Prot: P26951). Other names: CD123, IL3R, HIL-3Ra, IL3RAY, IL3RX, IL3RY
