DATA SHEET:  recombinant HUMAN TRAIL/Apo2L

Description: 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 apotosis, is achieved through binding to two dealth-signaling receptors, DR4 and DR5. These receptors belong to the TNFR transmembrane family of proteins and contain a cytoplasmic "death-domain" which activates the cells apoptotic machinery. This recombinant Human TRAIL/Apo2 Ligand is a 19.6 kDa protein consisting of 169 amino acid residues and comprises the full length of the TNF-like extracellular domain of Trail.

                    bulk sizes quoted on request

Supplied: Sterile filtered & lyophilized from 1X PBS No carrier.

Source: E. Coli

Purity: >98% by SDS-Page and HPLC analysis Endotoxin level is less than 0.1ng per ug (1EU/ug) of TRAIL/Apo2L.

Reconstitution: The lyophilized TRAIL/APO2L is soluble in most aqueous buffers. The lyophilized protein should be reconstituted in sterile DI water to a maximum concentration of 1mg/ml. Allow to set at least 30 minutes at 4 DEG C, tighten cap and rotate to reconstitute any material on sides of vial. If desired, you can centrifuge at 1000 rpm for 1 minute to concentrate volume in bottom of vial. This solution can be diluted into other buffered solutions containing carrier protein or medium and stored at -20 DEG C for future use. For most in vitro applications, TRAIL exerts its biological activity in the concentration range of 0.2 to 20.0 ng/ml.

Note:If this material is not to be used for coating or labeling (or other applications requiring carrier free material), the addition of 0.1% BSA to dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain stock >50ug/ml.

Storage: The lyophilized powder is stable at room temperature but it is best stored desiccated below 0 Deg C. Reconstituted TRAIL should be stored in working aliquots at -20DEG C. AVOID FREQUENT FREEZE THAW CYCLES.

Reactivity: TRAIL/Apo2 Ligand is fully biologically active when compared to standards. The ED(50) as determined by the dose dependent stimulation of IL-8 production by Human PBMC is less than 10ng/ml.The induction of apoptosis of LANCaP (human prostate cancer cells by Trail/Apo2L) was typically 2-3 fold higher after 48 hours using 0.1ug/ml.
