Recombinant human IL-3 (Cat.NO. HZ-1074) stimulates proliferation of TF-1 cell line (human erythroleukemic cell line) in a dose-dependent manner (blue curve, refer to bottom X-left Y). The activity of human IL-3 (0.5 ng/mL HZ-1074) is neutralized by mouse anti-human IL-3 monoclonal antibody 69004-1-Ig at serial dose (red curve, refer to top X-right Y). The ND50 is typically 0.8-2.4 ng/mL.
Interleukin-3 (IL-3) is a multilineage hematopoietic growth factor that promotes the proliferation, differentiation and survival of early multilineage hematopoietic progenitors. In particular, this cytokine plays a key role in stimulating the proliferation and survival of myeloid precursors. It is involved in a variety of cell activities such as cell growth, differentiation and apoptosis. This cytokine has been shown to also possess neurotrophic activity, and it may be associated with neurologic disorders (PMID: 24103757;2698876;2809196).
This antibody is used to Block/Neutralize IL3 protein.
