Recombinant mouse IL-3 (Cat. No. 575504) (black circles) induces the proliferation of M-NFS-60 cells. Ultra-LEAF™ purified anti-mouse IL-3 recombinant (clone QA19A69) (purple squares) inhibits the effect of recombinant mouse IL-3 (Cat. No. 575504) at 1 ng/mL of M-NFS-60 cells in a dose-dependent manner, whereas the GoInVivo™ purified mouse IgG1, κ isotype control (Cat. No. 400192) (gray triangles) does not have this effect. ND50 range: 0.05-0.15 µg/mL

IL-3 is the most potent growth factor for basophils followed by granulocyte-macrophage colony-stimulating factor and IL-5. These cytokines also act on mature basophils through specific receptors, thereby mediating adhesion, migration, and releasability. IL-3 is highly expressed by mast cells, and rapid and large amount of autocrine IL-3 production is responsible for mast cell survival by IgE in the absence of antigen. IL-3 has also been implicated in the pathogenesis of several chronic inflammatory diseases, including asthma, atherosclerosis, and neurodegenerative disorders, such as multiple sclerosis.

- Function
- Interleukine-3 is a pleiotropic factor which promotes both self-renewal and differentiation of early multipotential progenitors and is involved in inducible hematopoiesis in response to infections. IL-3 stimulates colony formation of megakaryocytes, neutrophils, and macrophages from bone marrow cultures.
- Interaction
- Erythroid cells, megakaryocytes, neutrophils, eosinophils, basophils, mast cells, monocytic lineages
- Ligand/Receptor
- Heterodimer IL-3Rα (CD123) and two alternate β-subunits, AIC2A binds IL-3 and is specific to IL-3Rα, AIC2B (CDw131) shared in common with IL-5R, GM-CSFR

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
