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.

Product Details
Alternative Name |

---|---|
Application Notes |
ELISA: binds to FN14 receptor at 10-100 ng/ml. |
Biological Activity |
Kills TWEAK sensitive cells. |
Concentration |
0.1mg/ml after reconstitution. |
Endotoxin Content |
<0.1EU/µg purified protein (LAL test; Bio Whittaker). |
Formulation |
Lyophilized. Contains PBS. |
MW |
~18-20kDa (SDS-PAGE). |
Purity |
≥90% (SDS-PAGE) |
Reconstitution |
Reconstitute with 100µl sterile water. Further dilutions should be made with medium containing 5% fetal calf serum. |
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. |
Specificity |
Binds to human and mouse Fn14 (TWEAK-R). |
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. |
UniProt ID |
