Mouse Granulocyte Macrophage-Colony Stimulating Factor Recombinant

• Background: GM-CSF is a monomeric protein of 127 amino acids with two glycosylation sites. The protein is synthesized as a precursor of 144 amino acids, which included a hydrophobic secretory signal sequence at the N-terminal end. The sugar moiety is not required for the full spectrum of biological activities. Non-glycosylated and glycosylated GM-CSF show the same activitiesin vitro. Fully glycosylated GM-CSF is biologically more activein vivothan the non-glycosylated protein. This protein is secreted together with other factors by T-cells and macrophages following cell activation by antigens or mitogens. Approximately 90% of the secreted colony stimulating activities are due to GM-CSF.
• Description: Recombinant mouse GM-CSF is a disulfide-linked monomer protein, consisting of 125 amino acids and migrates as an approximately 14 kDa protein under reducing conditions. Optimized DNA sequence encoding murine Granulocyte Macrophage-Colony Stimulating Factor mature chain was expressed inE. coli.
• UniProt: P01587
• Endotoxin: < 0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
• Purity: ≥ 95% by SDS-PAGE and HPLC
• Format: Lyophilized protein
• Reconstitution: Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
• Shipping Conditions: Gel Packs or Dry Ice
• Storage Conditions: The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
• Calculated Molecular Weight: 14 kDa
• Formulation: Lyophilized from 0.2 µm filtered PBS solution, pH 7.0.
