IL-3 Protein, Mouse

IL-3 Protein, Mouse functions via specific cell surface receptors to stimulate the proliferation, differentiation and survival of haematopoietic cell lines.

Interleukin-3 (IL-3) is aglycoprotein belonging to the hematopoietic growth factor family that in preclinical in vitro and in vivo studies has exhibited a multilineage activity. Recombinant human interleukin-3 (rhIL-3) enhances the mobilization of peripheral blood progenitor cells by recombinant human granulocyte colony-stimulating factor (rhG-CSF)^[1]. Human interleukin-3 (hIL-3) is a multipotent hematopoietic cytokine produced by mitogen and antigen-activated keratinocytes, T-lymphocytes, mast cells, NK cells, monocytes and endothelial cells. The hematopoietic progenitor cells are proliferated and differentiated with the help of hIL-3 protein into mature erythrocytes, mast cells, megakaryocytes and granulocytes. The potential use of hIL-3 protein has been extensively tested in various clinical applications such as bone marrow transplantation, hematological malignancies, cytopenias, aplastic anemia and various types of cancer^[2].

The ED₅₀ is <0.2 ng/mL as measured by M-NFS-60 cells, corresponding to a specific activity of >5.2 × 10⁶ units/mg.

  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized after extensive dialysis against PBS or 50 mM Tris-HCL, 300 mM NaCl, pH 8.0 or PBS, pH 7.4.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
