Activity:
Assay 1: The ED50 as determined by the dose-dependent stimulation of IL-8 production by human PBMC is less than 10 ng/ml. Assay 2: TWEAK weakly induces the death of HT29 cells when cultured in the presence of IFN-gamma. The ED50 for this effect is between 30-45 ng/ml.
Endotoxin:
Less than 0.01 ng/µg of protein (Less than 0.1 EU/µg).
Purity:
Greater than 98% by SDS-PAGE and HPLC
Storage:
If lyophilized, can be stored for 1 month at room temperature, 6 months at 4°C, or through the expiration date at -20°C to -80°C. Once reconstituted per the supplied instructions, can be stored for 3 months at -20°C to -80°C, or for 1 week at 2°C to 8°C. Avoid freeze-thaw cycles.
