Source:
Escherichia coli
Animal-free reagent and laboratory
Manufactured and tested under GMP guideline
 
Endotoxin level:
<0.1 EU per 1 μg of the protein by the LAL method.
 
Activity:
Measure by its ability to induce TF-1 cells proliferation. The ED50 for this effect is <80 pg/mL.
The specific activity of recombinant human GM-CSF is approximately >1 x 107 IU/mg.

Purity:
>98% as determined by SDS-PAGE analysis. Purified by Ni-NTA chromatography.
 
Formulation:
The protein was lyophilized from a solution containing 1X PBS, pH 8.0.
 
Reconstitution:
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
 
Storage:
Lyophilized protein should be stored at -20°C. This product is stable for one year upon receipt, when handled and stored as instructed. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C. Avoid repeated freeze/thaw cycles.
