CSF-1 drives macrophage survival, proliferation, and differentiation, making it indispensable for studying myeloid biology and tumor-associated immune microenvironments. This tag-free recombinant mouse CSF-1 (residues 33–262), produced in mammalian cells to preserve native glycosylation and folding, demonstrates exceptional signaling potency with an ED50 of 0.04–0.2 ng/mL in M-NFS-60 cell proliferation assays—supporting direct use in macrophage differentiation protocols, bone marrow-derived macrophage generation, and CSF1R/MAPK/PI3K signaling pathway dissection. Endotoxin levels below 1.0 EU/μg eliminate LPS-driven artifacts that confound innate immune cell assays, making this preparation appropriate for in vivo inflammation models and primary cell functional studies where contamination-free stimulation is critical. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, provides a suitable basis for use as a reference standard in CSF-1 detection assays or as a positive control in antibody validation workflows.
