Lyophilized recombinant human Interlerkin 3 (IL-3) remains stable up to 6 months at -80 °C from date of receipt. Upon reconstitution, rhIL-3 should be stable up to 1 week at 4 °C or up to 2 months at -20 °C.
Interleukin-3 (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 interleukin 3 expressed in CHO cells is glycosylated protein with molecular weight range from 17 to 30 kDa shown in non-reducing SDS-PAGE. Synonyms: MCGF (Mast cell growth factor), Multi-CSF, HCGF, P-cell stimulation factor
