General description
Product Source: E.coli
Human TRAIL (TNF-Related Apoptosis Inducing Ligand), also called APO2 Ligand, is a cytotoxic protein which activates rapid apoptosis in tumor cells, but not in normal cells. TRAIL-induced apoptosis, is achieved through binding to two death-signaling receptors, DR4 and DR5. These receptors belong to the TNFR transmembrane family of proteins and contain a cytoplasmic "death domain" which activates the cell′s apoptotic machinery. GF092 is a 19.6 kDa protein comprising the full-length of the TNF-like extracellular domain of TRAIL.

Physical form
Sterile filtered, then lyophilized from 0.3 mg/mL in 10mM Sodium Phosphate + 110 mM NaCl.
Storage and Stability
The lyophilized protein may be stored at room temperature for a few weeks, but is best stored at -20°C. After a quick spin, reconstitute in sterile water to a concentration of 0.5-1.0 mg/mL. This solution can be diluted into other buffered solutions and stored at 4°C for 1 week or -20°C for future use. Reconstituted GF092 should be stored in undiluted aliquots at -20°C for up to 6 months from date of receipt. Avoid repeated freeze/thaw cycles.
