特徴

• GM-CSF, also known as granulocyte macrophage colony-stimulating factor, is a hematopoietic growth factor that stimulates the development of neutrophils and macrophages and promotes the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. It is produced in by endothelial cells, monocytes, fibroblasts and T-lymphocytes. GM-CSF inhibits neutrophil migration and enhances the functional activity of the mature end-cells. Recombinant porcine GM-CSF was expressed in E. coli and purified by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer.
• Source:Recombinant protein corresponding to aa18-144 from porcine GM-CSF, fused to His-Tag expressed in E. coli.
