Gene Information

human ... IL3(3562)

General description

IL-3 is a species-specific colony-stimulating factor that stimulates colony formation of megakaryocytes, neutrophils, and macrophages from bone marrow cultures. Recombinant human IL-3 is a 15.0 kDa protein containing 133 amino acid residues.

Biochem/physiol Actions

Interleukin-3 (IL-3) is a hematopoietic growth factor. The gene encoding it is localized on human chromosome 5. It has a role in cell proliferation and activates different signaling cascades. It is crucial for the differentiation of hematopoietic-derived endothelial progenitor cells (EPCs). The differentiation of erythroid cells, mast cells and granulocytes is stimulated by IL-3. The protein has been linked to schizophrenia.

Physical form

Lyophilized without additives.

Reconstitution

Centrifuge the vial prior to opening. Avoid freeze-thaw cycles.
Reconstitute in water to a concentration of 0.1-1.0 mg/mL. The solution can then be diluted into other aqueous buffers.
