Product Specific Information

RMIL310 contains 134 amino acid residues.

Purity: >96% pure by SDS-PAGE and HPLC analysis.

Activity: One unit of activity is <0.1 ng/mL, as determined by proliferation assay of mouse IL-3-dependent FDC-P1 cells, corresponding to a specific activity of >1x10^7 units/mg.

Use: Interleukin-3 exerts activity in the range of 0.1 to 10 ng/mL for most in vitro applications.

Reconstitution and Dilution: Reconstitute in distilled water to a concentration of 100 µg/mL. After reconstitution, dilute cytokine in a neutral buffer containing carrier protein such as 5-10% FBS or 1-4% high purity BSA (fatty acid free fraction V).

Lyophilized product is stable until expiration if stored desiccated below 0ºC. Cytokines diluted as indicated above should be divided into aliquots and stored at -70ºC. Recombinant proteins should be stored at concentrations >500 ng/mL to reduce loss of activity.

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.
