Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) is hematopoietic growth factor produced by endothelial cells, monocytes, fibroblasts, and T cells. GM-CSF stimulates the production of neutrophilic granulocytes, macrophages, and mixed granulocyte-macrophage colonies from bone marrow cells. GM-CSF promotes immune system development and regulates neutrophil function during infection. Human and mouse GM-CSF show no cross-reactivity.

Activity Assay

Human GM-CSF (Animal-Free) is fully biologically active when compared to standard. The activity is determined by a proliferation assay using TF-1 cells and it is typically less than 200 pg/ml. This corresponds to an expected specific activity of 5 x 106 units/mg.
