Product Specification

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.
 
Applications:ELISA
 
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:Shipped on 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).
