Introduction
TNFSF12 is a cytokine that is part of the TNF ligand family. TNFSF12 is a ligand for the FN14/TWEAKR receptor. TNFSF12 has overlapping signaling functions with TNF, but displays a much wider tissue distribution. TNFSF12 induces apoptosis through multiple pathways of cell death in a cell type-specific manner. TNFSF12 promotes proliferation and migration of endothelial cells, and therefore acts as a regulator of angiogenesis. TNFSF12 is expressed in ***** heart, pancreas, skeletal muscle, small intestine, spleen and peripheral blood lymphocytes. TWEAK h induces NFkB and chemokine secretion. TNFSF12 exerts an apoptotic activity in HT-29 human adenocarcinoma cells whilst cultured in the presence of IFN-?. TNFSF12 promotes proliferation and migration of endothelial cells.
Description
TNFSF12 Human Recombinant (94-249 a.a.) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 156 amino acids and having a total molecular mass of 18kDa.
The TNFSF12 is fused with an 8 amino acids his tag at N-terminal (M-HHHHHH-R, total 164 a.a.) and purified by proprietary chromatographic techniques.
Source
Physical Appearance
Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered solution in PBS.
Solubility
It is recommended to reconstitute the lyophilized TNFSF12 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized TNFSF12 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TWEAK should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
