Product Details

Alternative Name:Tumor necrosis factor-α, TNFSF 2
MW:~19kDa (SDS-PAGE).
Source:Produced in E. coli. The extracellular domain of human TNF-α (tumor necrosis factor-α) (aa 85-223) is fused at the N-terminus to a linker peptide (8 aa) and a FLAG®-tag.
UniProt ID:P01375
Concentration:1mg/ml after reconstitution.
Formulation:Lyophilized. Contains PBS.
Purity:≥95% (SDS-PAGE)
Endotoxin Content:<0.1EU/µg purified protein (LAL test; Associates of Cape Cod).
Species reactivity:Human, Mouse
Specificity:Binds to human and mouse TNF-R1 and less efficiently to TNF-R2. In the presence of cross-linking enhancer (Prod. No. ALX-804-034), TNF-α shows a significantly higher affinity for TNF-R2 than for TNF-R1, mimicking the characteristics of membrane-bound TNF-α.
Application Notes:ELISA: binds to TNF-R2 at 0.1-10 ng.
Reconstitution:Reconstitute with 50µl sterile water. Further dilutions should be made with medium containing 5% fetal calf serum.
Shipping:Blue Ice
Long Term Storage:-20°C
Use/Stability:Stable for at least 6 months after receipt when stored at -20°C.
Handling:Avoid freeze/thaw cycles. After reconstitution, prepare aliquots and store at -20°C.
Technical Info/Product Notes:Historical lots have demonstrated biological activity in a concentration range of 0.1-1ng/ml (WEHI 164 cells), and an ED50 of 0.1ng/ml (WEHI 164 cells).

FLAG is a registered trademark of Sigma-Aldrich Co.
Regulatory Status:RUO - Research Use Only
