Recombinant Rat IL-3β

Product Details

Catalog Number: 400-03
Description:

IL-3 is a hematopoietic growth factor that promotes the survival, differentiation and proliferation of committed progenitor cells of the megakaryocyte, granulocyte-macrophage, erythroid, eosinophil, basophil and mast cell lineages.  Produced by T cells, mast cells and eosinophils, IL-3 enhances thrombopoiesis, phagocytosis, and antibody-mediated cellular cytotoxicity.  Its ability to activate monocytes suggests that IL-3 may have additional immunoregulatory roles.  Many of the IL-3 activities depend upon co-stimulation with other cytokines.  IL-3 is a species-specific, variably glycosylated cytokine.  Recombinant Rat IL-3β is a 16.3 kDa globular protein containing 144 amino acid residues.
