GM-CSF (CSF2) Active Protein | GM-CSF active protein

Recombinant Human GM-CSF (CSF2)

Cat. Num. AAA4159657

• Gene Names: CSF2; CSF; GMCSF
• Purity: >95% as determined by SDS-PAGE
• Synonyms: GM-CSF (CSF2); Recombinant Human GM-CSF (CSF2); GM-CSF; Granulocyte-macrophage colony-stimulating factor; CSF-2; Pluripoietin-alpha; Recombinant Human Granulocyte Macrophage Colony Stimulating Factor (CSF2); GM-CSF active protein

• Host: E Coli
• Purity/Purification: >95% as determined by SDS-PAGE
• Form/Format: Lyophilized from a 0.2 um filtered solution in Tris and NaCl
• Sequence Length: 144

• Bioactivity: 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
• Endotoxin Level: <1.0 EU/ug of recombinant protein as determined by the LAL method
• 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.
• Preparation and Storage: The lyophilized protein is stable for at least one year from date of receipt at-70 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2-8 degree C for one month, or at-20 degree C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Related Product Information for GM-CSF active protein

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.

NCBI Description

The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13. [provided by RefSeq, Jul 2008]
