Form : Lyophilized from sterile 50 mM Tris, pH 8.0.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Bio-activity : Measured in a cell proliferation assay using M-NFS-60 mouse myelogenous leukemia lymphoblast cell. The ED50 for this effect is typically 3-15 ng/mL.
Molecular Mass : The recombinant human CSF1 consists 461 amino acids and predicts a molecular mass of 51.9 kDa.
Protein Length : Met1-Arg255
Endotoxin : < 1.0 EU per μg protein as determined by the LAL method.
Purity : > 90 % as determined by SDS-PAGE.
Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
