Catalogue number
CYT-1015
Synonyms
Macrophage colony-stimulating factor 1, CSF-1, M-CSF, MCSF, Lanimostim.
Introduction
Granulocyte/Macrophage Colony-Stimulating Factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. MCSF induces cells of the monocyte/macrophage lineage. MCSF plays a role in immunological defenses, bone metabolism, lipoproteins clearance, fertility and pregnancy.
Description
MCSF produced in Sf9 Insect cells is a single, glycosylated polypeptide chain containing 231 amino acids (33-255 a.a.) and having a molecular mass of 26.1kDa (Molecular size on SDS-PAGE will appear at approximately 28-40kDa).
MCSF is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
Source
Sf9, Insect cells.
Physical Appearance
Sterile filtered colorless solution.
Formulation
MCSF protein solution (0.25mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Purity
Greater than 95.0% as determined by SDS-PAGE.
Biological Activity
Measured in a cell proliferation assay using M-NFS-60 mouse myelogenous leukemia lymphoblast cell. The ED50 for this effect is less or equal to 3 ng/ml.
