GMP Recombinant Human CSF1 Protein

Cat.No.: CSF1-110HG
Product Overview: Recombinant Human CSF1, Glu33-Ser190, was produced in E. coli using non-animal reagents in an animal-free facility under cGMP guidelines.
Source: E. coli
Species: Human
Form: Lyophilized from a 0.2 μm filtered solution in PBS.
Bio-activity: Measured in a cell proliferation assay using M‑NFS‑60 mouse myelogenous leukemia lymphoblast cells. Nakoinz, I. et al. (1990) J. Immunol. 145:860. The ED50 for this effect is typically 0.5-1.5 ng/mL.
The specific activity of Recombinant Human M-CSF is approximately 1.68 x 10^5 IU/μg, which is calibrated against recombinant human
M-CSF WHO International Standard (NIBSC code: 89/512).
Molecular Mass: Predicted Molecular Mass: 18.5 (monomer) kDa
SDS-PAGE: 37 kDa, reducing conditions
N-terminal Sequence Analysis: Met-Glu-Glu-Val-Ser-Glu-Try-(Cys)-Ser-His
Endotoxin: <0.01 EU per 1 μg of the protein by the LAL method.
Purity: >97%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Storage: Avoid repeated freeze-thaw cycles.
12 months, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution: Reconstitute at 50-500 μg/mL in PBS.
