Active Recombinant Human CSF1 Protein, Fc-tagged

• Cat.No.: CSF1-424H
• Product Overview: Recombinant human CSF1 (NP_757349.1) (Met1-Arg255) was expressed with the Fc region of human IgG1 at the C-terminus.

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: < 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.
