Fully biologically active when compared to standard. The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 0.5ng/ml, corresponding to a specific activity of >2.0×106IU/mg in the presence of actinomycin D.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, with 3mM DTT.
Endotoxin
Less than 0.1EU/μg of rMuTRAIL/TNFSF10 as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background
TNF-related apoptosis-inducing ligand (TRAIL), also known as Apo-2 ligand and TNFSF10, is a type II transmembrane protein with a carboxy-terminal extracellular domain that exhibits homology to other TNF superfamily members. Among TNF superfamily members, TRAIL is the most homologous to Fas Ligand, sharing 28% amino acid sequence identity in their extracellular domains. Murine TRAIL shares 65% amino acid sequence identity with human TRAIL.
