产品名：重组小鼠GM-CSF

产品号：LT-0235

产品信息：

GM-CSF在体外可刺激中性粒细胞和巨噬细胞的集落形成，并具有促进早期红巨核细胞、嗜酸性祖细胞增殖和发育的功能。GM-CSF是发现最早的对于DC有作用的细胞因子之一。GM-CSF在DC培养中的功能是促进单核细胞向大巨噬样细胞分化，促进细胞表面MHC Ⅱ类分子的表达，从而增强细胞的抗原递呈功能。此外，GM-CSF还可促进DC的存活。GM-CSF在多种肿瘤模型中表现出激活免疫反应的活性。GM-CSF抗肿瘤活性来源于其激活巨噬细胞和树突状细胞（DCs）的生物学功能。GM-CSF还能促进DC细胞成熟，促进共刺激分子上调和CD1d受体表达，从而参与抗原呈递功能。重组的小鼠GM-CSF是分子量为14.2kDa的球蛋白，有125个氨基酸组成。

别名：

Granulocyte-Macrophage Colony-Stimulating Factor, CSF-2, MGI-1GM, Pluripoietin-α

英文描述：

GM-CSF is a hematopoietic growth factor that stimulates the development of neutrophils and macrophages, and promotes the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. It is produced in endothelial cells, monocytes, fibroblasts and T-lymphocytes. GM-CSF inhibits neutrophil migration and enhances the functional activity of the mature end-cells. The human and murine molecules are species-specific and exhibit no cross-species reactivity. Recombinant Murine GM-CSF is a 14.2 kDa globular protein consisting of 125 amino acid residues.
