Scientific Data Images for Human IL-3 Antibody
Cell Proliferation Induced by IL-3 and Neutralization by Human IL-3 Antibody.
Recombinant Human IL-3 (Catalog # 203-IL) stimulates proliferation in the TF-1 human erythroleukemic cell line in a dose-dependent manner (orange line), as measured by the Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human IL-3 (1.25 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-3 Recombinant Monoclonal Antibody (Catalog # MAB603R). The ND50 is typically 0.1-0.3 µg/mL.Applications for Human IL-3 Antibody
Application
Recommended Usage
Neutralization
Measured by its ability to neutralize IL‑3-induced proliferation in the TF‑1 human erythroleukemic cell line. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The Neutralization Dose (ND50) is typically 0.1-0.3 µg/mL in the presence of 1.25 ng/mL Recombinant Human IL‑3.
Human IL-3 Sandwich Immunoassay
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: IL-3
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 at least two subunits, an IL-3 specific alpha chain which binds IL-3 with low affinity and a common beta chain that is shared by the IL-5 and GM-CSF high-affinity receptors. Although the beta chain itself does not bind IL-3, it confers high-affinity IL-3 binding in the presence of the alpha chain. Receptors for IL-3 are present on bone marrow progenitors, macrophages, mast cells, eosinophils, megakaryocytes, basophils and various myeloid leukemic cells.
