Active Recombinant Human CSF1 Protein, Pre-aliquoted

• Cat.No.: CSF1-12H
• Product Overview: Recombinant Human CSF1 Protein, Glu33 - Ser190, with an N-terminal Met, was expressed in E. coli.

Specification

• Description: The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of macrophages. The active form of the protein is found extracellularly as a disulfide-linked homodimer, and is thought to be produced by proteolytic cleavage of membrane-bound precursors. The encoded protein may be involved in development of the placenta. Alternate splicing results in multiple transcript variants.
• Source: E. coli
• Species: Human
• Bio-activity: Measured in a cell proliferation assay using M‑NFS‑60 mouse myelogenous leukemia lymphoblast cells. The ED50 for this effect is 0.5-1.5 ng/mL.
• Molecular Mass: Predicted Molecular Mass:18.5 kDa (monomer)
• Protein length: Glu33-Ser190, with an N-terminal Met
• N-terminal Sequence Analysis: Met
• Endotoxin: < 0.10 EU/μg of the protein by the LAL method.
• Purity: > 97% by SDS-PAGE under reducing conditions and visualized by silver stain.
• Stability: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 6 months from date of receipt at room temperature.
  • 12 months from date of receipt at 2-8 centigrade as supplied.
  • 1 month at 2-8 centigrade under sterile conditions after reconstitution.
  • 3 months at -20 to -80 centigrade under sterile conditions after reconstitution.
• Reconstitution: For a stock solution, reconstitute at 50-500 μg/mL in sterile PBS, or simply roll Pre-aliquoted directly into cell culture medium.
• Shipping: The product is shipped at ambient temperature.
