Scientific Data Images for Mouse IL‑3 Antibody

Cell Proliferation Induced by IL‑3 and Neutralization by Mouse IL‑3 Antibody.

Cell Proliferation Induced by IL‑3 and Neutralization by Mouse IL‑3 Antibody.

Recombinant Mouse IL‑3 (Catalog # 403-ML) stimulates proliferation in the M‑NFS‑60 mouse myelogenous leukemia lymphoblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL‑3 (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse IL‑3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-403-NA). The ND50 is typically 0.01-0.03 µg/mL.

Background: IL-3

Interleukin 3 is a pleiotropic factor produced primarily by activated T cells that can stimulate the proliferation and differentiation of pluripotent hematopoietic stem cells as well as various lineage committed progenitors. In addition, IL-3 also affects the functional activity of mature mast cells, basophils, eosinophils and macrophages. Because of its multiple functions and targets, it was originally studied under different names, including mast cell growth factor P-cell stimulating factor, burst promoting activity, multi-colony stimulating factor, thy-1 inducing factor and WEHI-3 growth factor. In addition to activated T cells, other cell types such as human thymic epithelial cells, activated mouse mast cells, mouse keratinocytes and neurons/astrocytes can also produce IL-3. At the amino acid sequence level, mature human and mouse IL-3 share only 29% sequence identity. Consistent with this lack of homology, IL-3 activity is highly species-specific and human IL-3 does not show activity on mouse cells.

IL-3 exerts its biological activities through binding to specific cell surface receptors. The high affinity receptor responsible for IL-3 signaling is composed of alpha and beta subunits. The IL-3R alpha is a member of the cytokine receptor super family and binds IL-3 with low affinity. Two distinct beta subunits, AIC2A ( betaIL-3) and AIC2B ( betac) are present in mouse cells. betaIL-3 also binds IL-3 with low affinity and forms a high affinity receptor with the alpha subunit. The betac subunits does not bind any cytokine but forms functional high affinity receptors with the alpha subunit of the IL-3, IL-5 and GM-CSF receptors. Receptors for IL-3 are present on bone marrow progenitors, macrophages, mast cells, eosinophils, megakaryocytes, basophils, and various myeloid leukemic cells.
