Description
Macrophage Colony-Stimulating Factor 1 (M-CSF) Rat, E. coli Recombinant Protein is a non-glycosylated homodimer, containing 2 x 155 amino acids and has a total molecular mass of 36.2 kDa. M-CSF is purified by proprietary chromatographic techniques.
Summary
Macrophage colony-stimulating factor (M-CSF) is a cytokine that plays an essential role in the regulation of survival, proliferation and differentiation of hematopoietic precursor cells, especially mononuclear phagocytes, such as macrophages and monocytes. Promotes the release of proinflammatory chemokines, and thereby plays an important role in innate immunity and in inflammatory processes. Plays an important role in the regulation of osteoclast proliferation and differentiation, the regulation of bone resorption, and is required for normal bone development. Required for normal male and female fertility. Promotes reorganization of the actin cytoskeleton, regulates formation of membrane ruffles, cell adhesion and cell migration. Plays a role in lipoprotein clearance. [Reference: UniProtKB - Q8JZQ0 (CSF1_RAT)].

Source
E. coli
Formulation
Sterile filtered white lyophilized (freeze-dried) powder. Lyophilized from a sterile filtered aqueous solution containing 10mM Na3PO4, pH 7.5.
Purity
Greater than 95.0% as determined by SDS-PAGE.
Biological Activity
The activity as determined by dose-dependent induction of M-NFS-60 cell proliferation is 1.65 ng/ml. This corresponds to an expected specific activity of 6.1x105 units/mg.
Reconstitution
It is recommended to reconstitute the lyophilized M-CSF in sterile 18M-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Shipping
At ambient temperature. Upon receipt, store the product at the temperature recommended below.
Storage/Expiration
Lyophilized M-CSF, although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution, M-CSF should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
