Analysis Note
Specific Activity: GF102 is fully biologically active when compared to standards. The ED50 as determined by the dose-dependent stimulation of IL-8 production by Human PBMC is less than 10ng/ml.
GF102 weakly induces the death of HT29 cells when cultured in the presence of IFN-g. The ED50 for this effect is between 30-45 ng/ml.

General description
Product Source: E.coli
Human TWEAK is a new secreted ligand in the tumor necrosis factor family that weakly induces apoptosis. TWEAK, like many members of the TNF family, was able to induce interleukin-8 synthesis in a number of cell lines. GF102 is a 17.0 kDa protein, comprising the TNF-like extracellular domain of TWEAK.

Physical form
Sterile filtered and then the protein was lyophilized from 10 mM NaP pH 7.5 + 0.1 M L-Arg.
Storage and Stability
The lyophilized protein is stable for a few weeks at room temperature, but best stored at -20°C. Freeze/thaw cycles will result in significant loss of activity. After a quick spin, reconstitute in 10 mM NaP pH 7.5 to a concentration of 1 mg/ml. This solution can be diluted into other buffer solutions or stored at -20°C. Reconstituted TWEAK should be stored at -20°C or lyophilized in working aliquots.
