Interleukin-3 (IL-3) is a potent growth promoting cytokine. This cytokine is capable of supporting the proliferation of a broad range of hematopoietic cell types. IL-3 is able to induce the differentiation of hematopoietic stem cells to precursor cells of myeloid lineage (erythrocytes, megakaryocytes, granulocytes, dendritic cells and monocytes). It is involved in a variety of cell activities such as cell growth, differentiation and apoptosis. IL-3 has been shown to also possess neurotrophic activity, and it may be associated with neurologic disorders. IL-3 is produced by activated T cells, mast cells.
Recombinant human IL-3 is a single, non-glycosylated polypeptide chain containing 134 amino acids.
Lyophilized from a sterile-filtered solution containing 0.1% Trifluoroacetic Acid (TFA).
> 95 % by SDS-PAGE
Fully biologically active when compared to standard. The ED50, as determined by a proliferation assay using human TF-1 cells, is typically < 0.25 ng/ml.
≤1 EU/µg of protein by kinetic LAL analysis.

Centrifuge vial prior to opening. Add sterile 10 mM acetic acid to a concentration of 0.1 mg/ml. DO NOT VORTEX. Allow several minutes for complete reconstitution. Further dilutions should be made in appropriate buffered solutions.
Upon receipt, store desiccated at -20°C for up to 1 year. Upon reconstitution, the preparation is stable for up to one month at 2-8°C. For long term storage, freeze in working aliquots and store at -20 to -80°C.
