Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a hematopoietic growth factor involved in the differentiation and activation of monocytes such as macrophages and dendritic cells, and granulocytes such as neutrophils, eosinophils, and basophils.

GM-CSF is commonly used in cell culture to stimulate the differentiation and maturation of human-induced pluripotent stem cells or peripheral blood monocytes to myeloid cells.

Qkine human GM-CSF is composed of 144 amino acids with a molecular weight of 14.6 kDa. This protein is animal origin-free, carrier protein-free, tag-free, and non-glycosylated to ensure a homogenous population with exceptional lot-to-lot consistency. Qk076 is suitable for reproducible and high-quality neutrophils and other relevant cell cultures.
