Purity:  >96% by SDS-PAGE and HPLC analyses.
Biological Activity:  Fully biologically active when compared to standard. The ED50 determined by a cell proliferation
 assay using human TF-1 cells is less than 0.1 ng/ml, corresponding to a specific activity of＞ 1.0 × 107 IU/mg.
Physical Appearance:  Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:  Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH 7.4.
Endotoxin:  Less than 1EU/μg of rHuGM-CSF as determined by LAL method.
Reconstitution:  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the
 bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a
 concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and
 stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
Storage:  This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage,
 preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For
 maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to
 -70°C. Avoid repeated freeze/thaw cycles.
Usage:  This material is offered by Shanghai Corning Bio-Tech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.

Human Granulocyte-Macrophage Colony Stimulating Factor
Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) was initially characterized as a growth factor that can support
the in vitro colony formation of granulocyte-macrophage progenitors. It is produced by a number of different cell types
(including activated T cells, B cells, macrophages, mast cells, endothelial cells and fibroblasts) in response to cytokine or
immune and inflammatory stimuli. Besides granulocyte-macrophage progenitors, GM-CSF is also a growth factor for erythroid,
megakaryocyte and eosinophil progenitors. On mature hematopoietic cells, GM-CSF is a survival factor for and activates the
effector functions of granulocytes, monocytes/macrophages and eosinophils. GM-CSF has also been reported to have a functional
role on non-hematopoietic cells. It can induce human endothelial cells to migrate and proliferate. Additionally, GM-CSF can also
stimulate the proliferation of a number of tumor cell lines, including osteogenic sarcoma, carcinoma and adenocarcinoma cell
lines. GM-CSF is species specific and human GM-CSF has no biological effects on mouse cells.
