Recombinant human macrophage colony-stimulating factor (M-CSF/CSF-1) produced in HEK293 cells and supplied as a tag-free, lyophilized protein for research use. It promotes monocyte-macrophage proliferation and differentiation and is used in immunology, oncology, hematopoiesis, and bone biology studies.
- Expressed in HEK293 cells, preserving eukaryotic glycosylation.
- Tag free for applications requiring native sequence.
- Purity greater than 95% by reducing SDS-PAGE.
- Apparent molecular weight ~23-28 kDa under reducing conditions.
- Lyophilized formulation for long-term storage; reconstitute per instructions.
- Biological activity ED50 approximately 0.4-3.0 ng/mL in cell proliferation assays.
- Suitable for macrophage proliferation, differentiation, polarization, and osteoclast studies.
