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
Granulocyte colony-stimulating factor (G-CSF/Csf3) is a key regulator of granulopoiesis and neutrophil mobilization, making precise functional studies dependent on highly potent, artifact-free recombinant material. This tag-free mouse Csf3 encompasses the full mature sequence (residues 31–208) and demonstrates exceptional signaling potency, with an ED50 below 0.05 ng/ml in NFS-60 cell proliferation assays — corresponding to a specific activity exceeding 2.0 × 10⁷ IU/mg — providing a reliable basis for dose-response characterization, JAK/STAT pathway activation studies, and neutrophil differentiation experiments. Endotoxin levels below 1.0 EU/μg satisfy the stringent criteria needed to prevent LPS-driven confounding in sensitive immune cell assays, supporting use in syngeneic mouse models of infection or tumor biology as well as serving as a quantitative reference standard in G-CSF detection assays. Purity exceeding 98% by SDS-PAGE further supports applications such as ELISA coating antigen preparation and antibody validation workflows where molecular homogeneity is essential.
