Description
|
Human Granulocyte Macrophage Colony Stimulating Factor (hGM-CSF), a hematopoietic growth factor, is mainly involved in granulopoiesis and monocytopoiesis. It is produced by T-cells and macrophages in response to antigens, and by endothelial cells and fibroblasts following induction of variouscytokines [1]. A monomeric protein of 127 amino acidswith six glycosylation sites and two intra disulfide bonds [2,3], glycosylated and non-glycosylated hGM-CSFs show similar biological activities [4].Other than its connection to the growth and development of granulocytes and macrophages, it is also indispensable for the proliferation of erythroid and megakaryocytic cells [5].
Recombinant human Granulocyte Macrophage Colony Stimulating Factor (rhGM-CSF) produced in E. coli is a non-glycosylated polypeptide. A fully biologically active molecule, rhGM-CSF has a molecular mass of 14 kDa analyzed by SDS-PAGE and is obtained by proprietary refolding and chromatographic techniques at Pepmic.
