Product Specific Information

Carrier-Free

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute lyophilized recombinant human IL-3 in sterile, distilled water to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤-20°C. Further dilution should be made in medium or buffered solution containing carrier protein, such as PBS with 0.1% BSA. Storage: Lyophilized recombinant human IL-3 should be stored at 2°C to 8°C, preferably desiccated. Store reconstituted recombinant human IL-3 at ≤-20°C (not in a frost-free freezer). Keep freeze-thaw cycles to a minimum.

Target Information

Interleukin 3 (IL-3), also called Mast Cell Growth Factor (MCGF), Multi-Colony Stimulating Factor (multi-CSF), or Eosinophil-CSF (E-CSF), is produced by activated T cells, mast cells and eosinophils. IL-3 is a hematopoietic growth factor that stimulates colony formation of erythroid, megakaryocyte, neutrophil, eosinophil, basophil, mast cell and monocytic lineages. Most of these functions are enhanced or dependent on co-stimulation with other cytokines. Human and mouse IL-3 share only 29% sequence identity at the amino acid level. The bioactivity of IL-3 is highly species specific. For example, human IL-3 has no activity on mouse cells. IL-3 is a potent growth promoting cytokine. IL-3 is capable of supporting the proliferation of a broad range of hematopoietic cell types, and 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.
