Recombinant human macrophage colony-stimulating factor (M-CSF, CSF-1) is supplied as a lyophilized, tag-free protein for in vitro research. It promotes proliferation and differentiation of mononuclear phagocyte lineage cells and is provided with confirmed purity and specific biological activity for cell-based assays and biochemical studies.
- Homodimeric hematopoietic growth factor that stimulates mononuclear phagocyte proliferation.
- Lyophilized, tag-free recombinant protein for flexible reconstitution.
- Expressed in E. coli to provide consistent material for assays.
- Greater than 95% purity as determined by reducing SDS-PAGE.
- High biological potency with ED50 in the low ng/mL range in M-NFS-60 proliferation assay.
- Available in small research sizes suitable for pilot studies and optimization.
- Stable when stored at -20°C; aliquot and freeze after reconstitution for long-term storage.
