Product Specification

Alternative Name:Apo-3L, TNFSF 12
MW:~18-20kDa (SDS-PAGE).
Source:Produced in E. coli. The extracellular domain of human TWEAK (aa 106-249) is fused at the N-terminus to a linker peptide (11 aa) and a FLAG®-tag.
UniProt ID:O43508
Concentration:0.1mg/ml after reconstitution.
Formulation:Lyophilized. Contains PBS.
Purity:≥90% (SDS-PAGE)
Endotoxin Content:<0.1EU/µg purified protein (LAL test; Bio Whittaker).
Species reactivity:Human, Mouse
Specificity:Binds to human and mouse Fn14 (TWEAK-R).
Biological Activity:Kills TWEAK sensitive cells.
Application Notes:ELISA: binds to FN14 receptor at 10-100 ng/ml.
Reconstitution:Reconstitute with 100µl 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 data has shown that TWEAK has a pro-apoptotic effect on several target cell lines, and it induces angiogenesis and proliferation in endothelial cells.

FLAG is a registered trademark of Sigma-Aldrich Co.
Figure: Apoptosis of TWEAK sensitive cells. Recombinant, human TWEAK exerts its full biological activity in a concentration range of 50-500ng/ml on Kym-1 cells.Method: Kym-1 cells (20’000 cells in 50µl RPMI medium containing 10% fetal calf serum) were incubated with the indicated concentrations of rhsTWEAK for 24 hours at 37°C in a 96 well plate. Concentrations of rhsTWEAK required to kill target cells may vary depending on cell type studied. Cell viability was determined using a PMS/MTS-based cell proliferation assay kit.
