Tag Info
Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Buffer
Lyophilized from a 0.2 μm filtered 20mM Tris-HCl, 1mM EDTA, pH 8.0.
Lead Time
Basically, we can dispatch the products out in 5-10 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
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
GM-CSF drives the proliferation and differentiation of myeloid progenitors, making it indispensable for generating bone marrow-derived dendritic cells and studying JAK/STAT5 signaling in murine immune models. This tag-free recombinant mouse Csf2, encompassing the full mature sequence (aa 18–141) expressed in *E. coli*, demonstrates potent bioactivity with an ED50 of 15–50 pg/mL in a PDC-P1 proliferation assay, confirming robust signaling capacity suitable for dose-response studies and functional differentiation experiments. Endotoxin levels below 1.0 EU/μg eliminate LPS-driven artifacts that confound cytokine-specific readouts in sensitive assays such as macrophage polarization, NF-κB pathway activation, and in vivo inflammation models. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, supports use as a reference standard in GM-CSF detection assays and as a reliable positive control for antibody validation by ELISA.
