Active Recombinant Human CSF1 Protein, Fc-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : Fc | 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 : | 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°CStore 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.
