|Source/Host||HEK 293 cells|
|Sequence||Human IL-3 (aa 20-152) is fused at the C-terminus to a His-tag.|
|Biological Activity||Measured by its ability to stimulate the proliferation of human TF-1 cells. The ED50 for this effect is typically 0.1ng/ml, corresponding to a specific activity of 1x 107 units/mg|
|Endotoxin Content||<0.01EU/μg protein (LAL test; Lonza).|
Reconstitute 10µg vial with 100 µl sterile water to a concentration of 0.1mg/ml.
Reconstitute 50µg vial with 100 µl sterile water to a concentration of 0.5mg/ml.
Add 1X PBS to the desired protein concentration.
|Formulation||Lyophilized from 0.2μm-filtered solution in PBS.|

|Product Specification Sheet|
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 Human IL-3 is a 15.0 kDa globular protein containing 133 amino acid residues.
