|Purity Confirmation||>98% by SDS-PAGE|
|Molecular Weight||15.0 kDa|
|N Terminal Sequence||MAPMTQT|
|Endotoxin Levels||< 0.1 ng per µg (IEU/µg) of rh IL-3|
|Biological Activity||The ED50 as determined by the dose-dependent stimulation of the proliferation of TF-1 cells is < 0.1 – 0.5 ng/ml. The WHO standard #91/510 was used as a control.|
|Reconstitution||The lyophilized IL-3 should be reconstituted in water to a concentration not less than 100µg/ml. This solution can be diluted into other buffered solutions or stored at -20°C for future use.|
|Stability and Storage||The lyophilized IL-3, though stable at room temperature, is best stored desiccated below 0°C. Reconstituted IL-3 should be stored in working aliquots at -20°C.|
|Synonyms||IL3; IL-3; MCGF; MULTI-CSF|
|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 thrombopoieses, 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 species-specific, variably glycosylated cytokine. Recombinant human IL-3 is a 15.0 kDa globular protein containing 133 amino acid residues.|
