  • Immunofluorescence staining of Hela cell with CSB-RA006047MA1HU at 1:100, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Human IgG(H+L).

Description

CSF2RB, also known as the common beta chain or CD131, serves as a critical shared signaling subunit for the receptors of GM-CSF, IL-3, and IL-5. This positioning at the convergence of multiple cytokine pathways makes CSF2RB essential for understanding hematopoietic cell development, immune cell activation, and inflammatory responses. Researchers investigating myeloid cell biology, allergic inflammation, or cytokine signaling networks will find CSF2RB detection particularly valuable for dissecting these interconnected pathways.

This recombinant monoclonal antibody, clone 9C9, offers the reproducibility and consistency that demanding experimental workflows require. Because recombinant antibodies are produced from defined sequences rather than hybridoma-derived sources, researchers can expect reliable performance across experiments and between lots, eliminating a common source of variability in longitudinal studies or multi-site collaborations. The human IgG1 isotype format and affinity-chromatography purification further ensure high specificity for your target.

Validation studies demonstrate effective performance in immunofluorescence applications, with successful staining confirmed in both HeLa and A549 human cell lines at 1:100 dilution. These experiments, using standard fixation with 4% formaldehyde and overnight primary antibody incubation at 4°C, produced clear signal detection when paired with FITC-conjugated secondary antibodies and DAPI counterstaining. The antibody is also validated for ELISA, providing flexibility for researchers who need both quantitative and spatial information about CSF2RB expression.

For immunology researchers studying cytokine receptor biology, hematopoietic disorders, or inflammatory conditions, this antibody provides a dependable tool for examining CSF2RB expression and localization in human samples. The validated immunofluorescence protocol offers a starting point that can be optimized for specific experimental contexts.

Target Background

Function
High affinity receptor for interleukin-3, interleukin-5 and granulocyte-macrophage colony-stimulating factor.
Gene References into Functions
  1. SYK mediates the actions of EPO and GM-CSF and coordinates with TGF-beta in erythropoiesis. PMID: 28131718
  2. Exome sequencing identified candidate variants, including a missense mutation in DUOX2 that impaired its function and a frameshift mutation in CSF2RB that was associated with Crohn's Disease in an independent cohort of Ashkenazi Jewish individuals. PMID: 27373512
  3. In a genetic analysis of Ashkenazi Jewish individuals, we associated Crohn's Disease with a frameshift mutation in CSF2RB. Intestinal monocytes from carriers of this mutation had reduced responses to granulocyte-macrophage colony-stimulating factor, providing an additional mechanism for alterations to the innate immune response in individuals with Crohn's Disease. PMID: 27377463
  4. VitD-mediated stimulation of GC anti-inflammatory affects human monocytes in a process involving GM-CSF and MED14 PMID: 23572530
  5. These data suggest that expression of GM-CSF and its receptor subunits by colon tumors may be a useful marker for prognosis PMID: 23108143
  6. JAK kinase binding to betac requires the presence of three critical betac lysine residues, and this binding event is essential for receptor ubiquitination, endocytosis, and signaling. PMID: 21965659
  7. Over expression of IL-3Ralpha and truncated mutation of hbetac may be involved in proliferation and differentiation block in NB4 cells. PMID: 21176354
  8. Granulocyte/macrophage colony-stimulating factor causes a paradoxical increase in the BH3-only pro-apoptotic protein Bim in human neutrophils PMID: 20705940

  10. Hereditary pulmonary alveolar proteinosis caused by recessive CSF2RB mutations [case report] PMID: 21205713
  11. the up-regulation of IL-3Rbeta expression may contribute to the maintenance of proliferation rather than cell differentiation. PMID: 21207215
  12. The beta1 integrin-interacting domain in the extracellular domain of IL-3Rbeta was identified. A fragment of a protein corresponding to domain 4 of IL-3Rbeta prevented IL-3-mediated arterial morphogenesis and endothelial cell migration. PMID: 20802515
  13. the domain 1 D-E loop disulfide of hbetac and beta(IL-3) have roles in maintaining the precise positions of ligand-binding residues necessary for normal high affinity binding and signaling PMID: 20516062
  14. Two different modes of beta c binding are utilized in the presence of the hIL-3R alpha isoforms. PMID: 20472554
  15. hGM-CSF activation of hGM/beta(c)with or w/o the hbeta(c) subunit, promoted primitive phenotype maintenance, indicating that the hGM Ralpha chain cytosolic domain is needed for differentiation mediated by the hGM Ralpha, beta(c) receptor complex. PMID: 12384414
  16. JAK2 activation mediates cross-talk between extracellular domain mutants of the beta-subunit of the GM-CSF receptor and EpoR PMID: 12488507
  17. Interleukin-3 binding to the human betac receptor involves functional epitopes formed by domains 1 and 4 of different protein chains PMID: 15060062
  18. A minor improvement in resolution has given a clearer indication of the position and stabilization of the key residues Tyr15, Phe79, Tyr347, His349, Ile350 and Tyr403 in the elbow region between domain 1 and domain 4 of the dimer-related molecule. PMID: 16754968
  19. These results suggest that the JAK1-JH7-3 domains are required for interleukin-3 receptor common beta subunit interaction and abolish wild type JAK1 and JAK2-mediated signaling. PMID: 16767694
  20. This study found that several markers (rs2072707, rs2284031 and rs909486)of csf2rb showed sex-specific and family history-dependent associations with schizophrenia. PMID: 17667962
  21. The dynamic role of the common signaling subunit beta c is to prevent IL5alpha and GM-CSF ligand-receptor complexes from rapidly dissociating. PMID: 18294864
  22. The interaction between intercellular adhesion molecule 1 (ICAM-1) and the GM-CSF receptor is essential for GM-CSF-induced eosinophil activation and survival. PMID: 18322230
  23. IL-5-induced effects on betac assembly in the presence of nontagged IL-5Ralpha provide direct evidence that IL-5 can cause higher order rearrangements of betac homo-oligomers PMID: 18326494
  24. Ligand-binding and receptor activation are not critically dependent on individual N-glycosylation sites within the IL-3- and IL-5-receptor common beta-subunit. PMID: 18374598
