• Assay Protocol:

  Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to ‑80°C.

• Endotoxin:

  < 0.1 ng/µg of protein (< 1EU/µg)

• Purity:

  > 98% by SDS-PAGE & HPLC analyses

• Bioactivity:

  Assay #1: Determined by its ability to induce apoptosis in HeLa cells. The expected ED50 for this effect is 5.0-10.0 ng/ml. Assay #2: The ED50 was determined by a cytotoxicity assay using HT-29 cells is ≤ 0.05 ng/ml (> 2 x 107 units/mg) .
