Lead Time
5-10 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Description
Macrophage colony-stimulating factor 1 (CSF-1) is a key regulator of monocyte and macrophage survival, proliferation, and differentiation, making it indispensable for studying myeloid lineage biology. This tag-free recombinant mouse Csf1 (residues 33–262) demonstrates strong signaling potency, with an ED50 below 2 ng/ml in M-NFS-60 proliferation assays corresponding to a specific activity exceeding 5.0 × 10⁵ IU/mg — performance that supports use in macrophage differentiation protocols, JAK/STAT and MAPK pathway dissection, and as a reference standard in cytokine detection assays. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound functional readouts in primary macrophage cultures and in vivo inflammation or tumor biology models. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, provides a suitable basis for antibody validation workflows including ELISA standard curves and Western blot positive controls.
