- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
Data Display
Human IL-3 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Human IL-3 is greater than 95% as determined by SEC-HPLC.
Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. The ED50 for this effect is 0.15 - 0.75 ng/mL (QC Test).
Background
Interleukin 3 is a pleiotropic factor produced primarily by activated T cells that can stimulate the proliferation and differentiation of pluripotent hematopoietic stem cells as well as various lineage committed progenitors. This CSF induces granulocytes, macrophages, mast cells, stem cells, erythroid cells, eosinophils and megakaryocytes.
