Recombinant Human soluble Trail also called TNF-related apoptosis-inducing Ligand, TNFSF10, Apo2 Ligand AND TL2 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 168 amino acids and having a molecular mass of 19.6kD. TRAIL is purified by proprietary chromatographic techniques.

Amino Acid Sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Arg-Glu-Arg-Gly-Pro.

Biological Activity:
Recombinant Human TRAIL is fully biologically active when compared to standard. The activity is determined by the ability to induce apoptotic cell death in TRAIL-sensetive U343MG cells, ED50 for this effect is 1-3 ng/ml.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O, 0.1% HSA or BSA. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
19.6kD
Source: E. coli
Purity: 97% (RP-HPLC, SDS-PAGE)
Concentration: ~1mg/ml
Form: Supplied as a lyophilized powder from 150mM sodium chloride, 50mM sodium phosphate, pH 7. Reconstitute with sterile ddH2O, 0.1% BSA or HSA to >0.1mg/ml.
