- Molecular Characterization
This protein carries no "tag".
The protein has a calculated MW of 14.5 kDa. The protein migrates as 18-26 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 0.1 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

- BackgroundGranulocyte-macrophage colony-stimulating factor (GM-CSF) is also known as Colony stimulating factor 2 (granulocyte-macrophage), is a cytokine initially characterized by its ability to induce colonies of granulocytes and macrophages from myeloid progenitor cells, and is secreted by macrophages, T cells, mast cells, endothelial cells and fibroblasts. GM-CSF is a cytokine that functions as a white blood cell growth factor. GM-CSF stimulates stem cells to produce granulocytes (neutrophils, eosinophils, and basophils) and monocytes. Monocytes exitthe circulation and migrate into tissue, whereupon they mature into macrophages and dendritic cells. Thus, it is part of the immune/inflammatory cascade, by which activation of a small number of macrophages can rapidly lead to an increase in their numbers, a process crucial for fighting infection. The active form of the protein is found extracellularly as a homodimer. Human GM-CSF glycosylated in its mature form. As a part of the immune/inflammatory cascade, GM-CSF promotes Th1 biased immune response, angiogenesis, allergic inflammation, and the development of autoimmunity, and thus worthy of consideration for therapeutic target. GM-CSF has also recently been evaluated in clinical trials for its potential as a vaccine adjuvant in HIV-infected patients. The preliminary results have been promising. GM-CSF is also used as a medication to stimulate the production of white blood cells following chemotherapy.

Thy-1、c-kit散在分布于HB组织中,主要集中在汇管区,而正常肝脏组织中不表达;CD34及SCF在HB中的表达明显高于正常肝脏组织(P0.05),其中CD34主要在血管内皮系统中分布,SCF主要表达在汇管区;CD56表达于成簇的神经纤维组织中,在HB及正常肝脏组织中表达差异无统计学意义(P0.05)。结论不同干细胞相关表面标志物分布于HB组织中,并且集中表达在特定区域。表达Thy-1/c-kit阳性细胞可能对HB的发生起一定作用。
有几个疑问
1：荧光标记到细胞是标记到细胞表面还是细胞质内？
2：荧光应该随着细胞的分化和增殖逐渐消失？是不是分化增殖越快，荧光消失速度越快？
3：有哪些容易操作，成本便宜的荧光物质？
谢谢各位战友
可以用CCR3的抗体标记其他细胞，再反推中性粒细胞所占的比例吗？肺泡灌洗液中主要有嗜酸性粒细胞，淋巴细胞，中性粒细胞和巨噬细胞。
1，逆转录病毒将GFP基因导入干细胞，这种办法在导入基因时好像比较麻烦，但是检测好像比较简单。
2，将雄性干细胞植入雌性动物，追踪Y染色体，即SRY基因，但是看文献上说SRY追踪的FISH技术复杂，费用高，但是还没有看到具体的技术步骤，也不知道具体要多少费用。
请多指教
比如你用的CD1a－FITC（如果是鼠单抗IgG1，那对照抗体就要用相同物种的非特异性IgG1-FITC）。注意浓度要相同。一般提供抗体的公司BD，santa cruz等有提供的。其他就按照说明书的推荐浓度和孵育时间。
