Granulocyte colony-stimulating factor (G-CSF) is a member of the hematopoietic growth factor family which plays a crucial role in the proliferation, differentiation, and maturation of committed progenitor cells to granulocytes, such as neutrophils. G-CSF is produced by various cell types including macrophages, fibroblasts, and endothelial cells. It binds to the G-CSF surface receptors upon stimulation to activate key cellular processes involved in neutrophil proliferation, maturation, and mobilization in healthy and diseased states.

G-CSF is commonly used in vitro to maintain neutrophils and stimulate the differentiation of cells to neutrophil lineage. is a highly pure, bioactive glycoprotein produced in an animal-free expression system composed of 174 amino acids with a molecular weight of 18.6 kDa. Human and murine G-CSF are 73% identical at the amino acid level and show species cross-reactivity.

Human G-CSF is carrier-free, tag-free, and non-glycosylated to ensure a pure and homogenous production of high-quality neutrophils and other relevant cell cultures with exceptional lot-to-lot consistency.
