Description of Human IL-3, cct-premium
Recombinant human Interleukin-3 (IL-3) is a 15.0 kDa globular protein containing 134 amino acid residues. It 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.
The ED50 of ≤ 0.1 ng/ml was determined by the dose dependent stimulation of the proliferation of TF-1 cells. It corresponds to a specific activity of ≥ 1 x 107 units/mg.
We recommend a quick spin followed by reconstitution in sterile filtered water to a concentration not less than 100 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
The lyophilized protein is stable at room temperature for up to 1 month, at 4°C for up to 6 months, and at -20°C to -80°C until expiry date. Working aliquots stored with a carrier protein are stable for at least 12 months at -20°C to -80°C. Please avoid repeated freeze-thaw cycles.
