Recombinant Human GM-CSF Protein_C230358

GM-CSF (Granulocyte-Macrophage Colony-Stimulating Factor) is a cytokine that belongs to the colony-stimulating factor family. It plays an important role in immunomodulation, hematopoiesis and inflammation.GM-CSF is mainly produced by a variety of cells, including macrophages, T cells, B cells and fibroblasts.It is produced by a variety of cells, including macrophages, T cells, B cells and fibroblasts. It can stimulate the proliferation, differentiation and functional activation of granulocytes and monocytes in the hematopoietic cell lineage.GM-CSF can promote the differentiation of pluripotent stem cells in the bone marrow to granulocytes and monocytes, increase the number of leukocytes, and improve their function, thus enhancing the body's immune response and anti-infection ability. In addition, GM-CSF has an important role in regulating the activation of macrophages and dendritic cells and anti-microbial activity. In clinical practice, GM-CSF is widely used in the treatment of bone marrow transplantation-related complications, malignant tumors, and immunodeficiency. It is also used as a tool in laboratory studies to explore the regulatory mechanisms of the hematopoietic and immune systems and to develop new therapeutic strategies. This recombinant human GM-CSF is supplied as a lyophilized powder with high activity, high purity, low endotoxin, and no redundant labeling.   Product Properties Synonyms Granulocyte/Macrophage Colony-Stimulating Factor, GM-CSF, CSF-2, MGI-1GM, Accession P04141 Source E.coli-derived human GM-CSF protein, Ala18-Glu144.
