产品编号：CYT-308
产品规格：2μg/10μg/1mg

Synonyms	Macrophage Colony Stimulating Factor, CSF-1, Lanimostim, MCSF, MGC31930, M-CSF.
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. CSF-1 induces cells of the monocyte/macrophage lineage. It plays a role in immunological defenses, bone metabolism, lipoproteins clearance, fertility and pregnancy.
Description	Macrophage Colony Stimulating Factor Human Recombinant produced in E.coli is a disulfide linked homodimer, non-glycosylated, polypeptide chain containing 2 x 159 amino acids and having a total molecular mass of 36.8 KD. MCSF is purified by proprietary chromatographic techniques.
Source	Escherichia Coli.
Physical Appearance	Sterile Filtered White lyophilized （freeze-dried） powder.
Formulation	The protein was lyophilized with 5mM NaP, pH-8.0 & 100mM NaCl.
Solubility	It is recommended to reconstitute the lyophilized M-CSF in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Stability	Lyophilized Macrophage Colony Stimulating Factor although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution MCSF should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.
Amino acid sequence	The sequence of the first five N-terminal amino acids was determined and was found to be Met-Glu-Glu-Val-Ser.
Purity	Greater than 97.0% as determined by（a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE.
Biological Activity	The ED50, calculated by the dose-dependant stimulation of the proliferation of murine M-NFS-60 indicator cells was found to be < 2.0ng/ml.
Usage	ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
