Cat. No.	Z100275
Name	Recombinant Human GM-CSF (CSF2) (E. coli)
Description	GM-CSF is a hematopoietic growth factor that is produced by endothelial cells, monocytes, fibroblasts and T-lymphocytes following their activation by antigens or mitogens. GM-CSF stimulates the development of macrophages and neutrophils and plays a role in the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. Approximately 90% of the secreted colony stimulating activities are due to GM-CSF. While non-glycosylated and glycosylated GM-CSF show similar activities in vitro, fully glycosylated GM-CSF is biologically more active in vivo compared to its non-glycosylated counterpart. Human and murine GM-CSF are species-specific and therefore, exhibit no cross-reactivity. Recombinant Human GM-CSF is a non-glycosylated, monomeric protein that contains intra-chain disulfide bonds.

Appearance	Lyophilized Powder
Molecular Weight	15 kDa
Endotoxin Level	<1.0 EU/µg of recombinant protein as determined by the LAL method
Purity	>95% as determined by SDS-PAGE
Formulation	Lyophilized from a 0.2 μm filtered solution in Tris and NaCl
Function	The ED50 as determined by the dose-dependent stimulation of the proliferation of human TF-1 cells was found to be ≤ 0.5 ng/mL
Reconstitution	A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage	The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage	For research use only. Not for diagnostic or therapeutic use.

How do I choose the right growth factor for my experiment?

Cell type: Different cells respond to different growth factors. Choose a growth factor that promotes the growth or differentiation of your target cell type.
Desired outcome: Whether you are studying proliferation, differentiation, or survival, different growth factors will promote different cellular behaviors.
Concentration and formulation: Different experiments may require varying concentrations of growth factors.
