M-CSF (Macrophage colony-stimulating factor) is a potent lineage restricted haematopoietic growth factor and member of the CSF family of hormone-like glycoproteins, which plays a key role in the regulation of cellular differentiation, proliferation, and the survival of blood monocytes, tissue macrophages and their progenitor cells.
Along with sRANKL/CD254/OPGL, M-CSF is essential for osteoclastogenesis, acting through the tyrosine kinase receptor c-fms (colony stimulating factor 1 receptor), and facilitates haematopoietic recovery following bone marrow transplantation.
Purified recombinant protein - lyophilised
Reconstitute with 0.1ml distilled water. For extended storage the addition of 0.1% BSA is recommended. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
Purified recombinant M-CSF expressed in E.coli
The ED50, determined by the dose-dependent stimulation of the proliferation of M-NSF-60 cells, was ≤ 1 ng/ml corresponding to a specific activity of ≥ 1 x 106 units/mg.
= 98% by SDS PAGE and HPLC analysis
