Description
GenieKine Recombinant Human M-CSF/CSF1 Protein (GKRP0016)
GenieKine Recombinant Human M-CSF/CSF1 Protein is expressed in CHO cells. M-CSF drives the survival, proliferation and differentiation of monocytes into macrophages, and is used to generate human monocyte-derived macrophages. Supplied as a lyophilized powder with purity of >97% by SDS-PAGE and endotoxin below 0.02 EU/µg by LAL assay. Suitable for immune cell culture and stem cell culture. For research use only.
This product (SKU: GKRP0016) is expressed in CHO cells as a disulfide-linked homodimer and is supplied unconjugated. It has a calculated molecular weight of 25.1 kDa (monomer) and an observed molecular weight of 43 kDa (reducing), 86 kDa (non-reducing) on SDS-PAGE. Purity is >97% by SDS-PAGE and endotoxin is <0.02 EU/µg by the LAL method.

Macrophage Colony-stimulating Factor (M-CSF), also known as CSF-1, is a cytokine with roles in the growth, differentiation, and survival of monocytes and macrophages. M-CSF promotes the differentiation of monocytes into mature tissue-resident macrophages involved in the phagocytosis of pathogens, clearance of debris, and secretion of growth factors for tissue repair. In addition, M-CSF is involved in regulating bone homeostasis by stimulating osteoclast differentiation and activity. M-CSF is primarily produced by monocytes and macrophages themselves. It acts in an autocrine and paracrine manner to regulate the proliferation, differentiation, and survival of these cells. However, M-CSF is also produced in bone marrow stromal cells, fibroblasts and endothelial cells as a component in the local microenvironmental regulation of the immune cell function. M-CSF is often highly expressed in the tumor microenvironment where it recruits tumor-associated macrophages (TAMs) that suppress the native immune response leading to tumor progression and infiltration. M-CSF binds M-CSF R (CD115), a Receptor Tyrosine Kinase (RTK) family III member.
