Recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) is produced in CHO cells to ensure proper folding, glycosylation, and full biological activity. Supplied in a tag-free format, this cytokine preserves its native conformation, making it ideal for applications in immunology, hematopoiesis, and cell therapy research.

GM-CSF is a hematopoietic growth factor that regulates the survival, proliferation, and differentiation of granulocyte and macrophage progenitors. It also enhances the function of mature monocytes, macrophages, and dendritic cells, playing a critical role in host defense, inflammation, and immune regulation. Recombinant GM-CSF is widely used in immune cell culture, dendritic cell generation, and studies of hematopoietic and inflammatory pathways.
