Recombinant Human GM-CSF (CSF2)

Recombinant Human GM-CSF (CSF2)

• 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.
• CAS Number: 9000-83-3

• Gene ID: 1437
• Accession Number: P04141
• Organism: Human
• Source: E. coli
• Concentration: <1.0 EU/μg of recombinant protein as determined by the LAL method
• Purity: >95% as determined by SDS-PAGE
• Solubility: 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.
• 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

• Storage Conditions: 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.
