Human GM-CSF Protein
Recombinant Human GM-CSF Protein is expressed from E.coli without tag. It contains Ala18-Glu144.[Accession | P04141]
The protein has a predicted MW of 14.6 kDa same as Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human GM-CSF on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
The purity of Human GM-CSF is greater than 95% as determined by SEC-HPLC.
Immobilized Human GM-CSF at 2μg/ml (100μl/Well) on the plate. Dose response curve for Human GM-CSF R alpha, hFc Tag with the EC50 of 16.9ng/ml determined by ELISA (QC Test).
Human GM-CSF R alpha, His Tag captured on CM5 Chip via anti-His antibody can bind Human GM-CSF, No Tag with an affinity constant of 0.79nM as determined in SPR assay (Biacore T200).
The ED50 as determined by the dose-dependent stimulation of the proliferation of human TF-1 cells is 0.02-0.1 ng/mL (QC Test).
Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony-stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, natural killer cells, endothelial cells and fibroblasts that functions as a cytokine. The pharmaceutical analogs of naturally occurring GM-CSF are called sargramostim and molgramostim.
