Purity

＞97% by SDS-PAGE or HPLC.

Biological activity

Fully biologically active when compared to standard.  rHusTRAIL-R2 reduced the production of LPS-induced TNF by its ability to neutralize endogenous TRAIL in fresh human PBMC. In this assay, endogenous TRAIL is induced during a 24-hour exposure to LPS (10 ng/mL) but in the presence of rHusTRAIL-R2, TRAIL-induced TNF is suppressed.

Formulation

Lyophilized from a 0.2µm filtered concentrated solution in 20mM PB, 150mM NaCl, pH7.4.

Endotoxin level

＜0.1EU/μg rHusTRAILR2/TNFRSF10B protein as determined by LAL method.
