IL3RA/CD123 Antibody recognizes endogenous levels of total IL3RA/CD123 protein.
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human IL3RA/CD123 protein. Antibodies are purified by peptide affinity chromatography.
IL3RA/CD123 is the alpha subunit of an IL-3 receptor that also contains the common beta chain (βc) shared with receptors for other cytokines. IL3RA/CD123 alone binds to IL-3 with high specificity but low affinity and it does not transduce intracellular signaling, while βc alone does not bind to IL-3 appreciably. Together, IL3RA/CD123 and βc form the functional high-affinity receptor for IL-3. IL3RA/CD123 is mainly expressed on the hematopoietic progenitor cells, primarily the granulocytic and monocytic linages (1,2). IL3RA/CD123 is highly expressed on leukemic stem cells in the majority of AML (acute myeloid leukemia) patients and is correlated with poor prognosis. In addition, overexpression of IL3RA/CD123 has also been reported for other hematopoietic malignancies (3-5). It is considered as a valuable therapeutic target for these malignancies (6-8).
