izTRAIL, Soluble (human) (rec.)
Product Details | |
---|---|
Synonyms | Apo-2L; TNFSF10; CD253 |
Product Type | Protein |
Properties | |
Source/Host | E. coli |
Sequence |
The extracellular domain of human TRAIL (aa 95-281) is fused at the N-terminus to an isoleucine zipper motif. |
Crossreactivity |
Dog Human |
Specificity |
Binds to human TRAIL receptors 1-4 (TRAIL-R1 to TRAIL-R4); izTRAIL does not interact with the apoptosis-inducing mouse TRAIL receptor (TRAIL-R). |
Biological Activity |
Induces apoptosis in vitro in different human cancer cell lines with an EC50 of 5-200ng/ml, depending on the individual cell line used. Recombinant izTRAIL does not kill 4-day cultures of primary human hepatocytes (PHH) at concentrations of at least up to 1μg/ml (Ganten 2006). Good bioavailability in vivo, shows no toxic effects in mice at doses of at least up to 500μg per day (Wissink 2006). |
MW |
~82kDa as stable trimers (determined by size exclusion chromatography) ~28kDa as monomer (determined by SDS-PAGE) |
Purity | ≥95% (SDS-PAGE) |
Endotoxin Content | <0.01EU/μg purified protein (LAL test; Lonza). |
Concentration | 0.1mg/ml after reconstitution. |
Reconstitution | Reconstitute with 100μl sterile water. |
Formulation | Lyophilized. Contains 20mM TRIS-Cl, 0.5M arginine-HCl, 100mM NaCl, 0.02% Tween 20. |
Other Product Data |
UniProt link P50591: TRAIL (human) |

izTRAIL is a newly available, highly active recombinant form of soluble human TRAIL. Due to a trimerizing N-terminal isoleucine zipper (iz) motif the intrinsic trimerization of TRAIL, required for apoptosis-inducing activity of TRAIL, is enhanced when compared to non-tagged soluble human TRAIL (shTRAIL). Therefore, izTRAIL is a potent inducer of apoptosis in many human cancer cells, but not normal human hepatocytes. In addition, the half-life of izTRAIL is about eight-fold higher than the half-life of shTRAIL. These properties render izTRAIL highly suitable for both, in vitro and in vivo use, particularly for studies in which investigators plan to transfer their in vitro results into an in vivo system with human cancer cells in xenotransplant settings examining susceptibility to TRAIL-induced apoptosis.
