Human and Cynomolgus CSF1 sequences are identical. 種屬: Human 表達宿主: Human Cells M-CSF / CSF-1蛋白質控指標 純度: > 95 % as determined by SDS-PAGE SDS-PAGE 內**: < 1.0 EU per μg of the protein as determined by the LAL method 穩定性: Samples are stable for up to twelve months from date of receipt at -70℃ 預測N端: Glu 22 分子量: The recombinant human CSF1 consists of 169 amino acids and predictes a molecular mass of 19.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCSF1 is approximately 27-32 kDa band due to glycosylation 緩沖液: Lyophilized from sterile PBS , pH 7.4 Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. Please contact us for any concerns or special requirements. M-CSF / CSF-1蛋白使用指南 儲存方法: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information. M-CSF / CSF-1蛋白背景綜述 Macrophage colony-stimulating factor 1, also known as CSF-1, M-CSF, Lanimostim and CSF1, is a single-pass membrane protein which is disulfide-linked as a homodimer or heterodimer. Granulocyte / macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. Macrophage colony-stimulating factor (MCSF) is known to facilitate monocyte survival, monocyte-to-macrophage conversion, and macrophage proliferation. M-CSF / CSF-1 is a secreted cytokine which influences hemopoietic stem cells to differentiate into macrophages or other related cell types. It binds to the Colony stimulating factor 1 receptor. M-CSF / CSF-1 may also be involved in development of the placenta. The active form of M-CSF / CSF-1 is found extracellularly as a disulfide-linked homodimer, and is thought to be produced by proteolytic cleavage of membrane-bound precursors. M-CSF / CSF-1 induces cells of the monocyte/macrophage lineage. It also plays a role in immunological defenses, bone metabolism, lipoproteins clearance, fertility and pregnancy. Upregulation of M-CSF / CSF-1 in the infarcted myocardium may have an active role in healing not only through its effects on cells of monocyte/macrophage lineage, but also by regulating endothelial cell chemokine expression. 參考文獻 Pandit J. et al., 1992, Science 258:1358-1362.
