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 1xPBS, pH 7.4
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
Mouse TNF-α drives NF-κB and MAPK signaling cascades central to inflammation, apoptosis, and tumor microenvironment remodeling, making cytotoxic potency and endotoxin control essential for meaningful experimental results. This tag-free recombinant protein, covering the mature soluble domain (aa 89–235) expressed in *E. coli*, demonstrates an ED50 of 2–8 pg/mL in an L-929 cytotoxicity assay with actinomycin D, confirming signaling potency suitable for cell-based apoptosis and activation assays, NF-κB reporter studies, and use as a reference standard in cytokine detection platforms. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound results in primary macrophage stimulation, dendritic cell maturation experiments, and *in vivo* tumor biology models. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin profile, supports use in antibody development workflows including immunization, ELISA coating, and Western blot positive controls.
