Biological Activity

Bcl-2 inhibitor (Ki values are 0.29 μM and 1.11 μM for Bcl-2 and Bcl-XL respectively). Inhibits the angiogenic potential of endothelial cells in vitro. Induces S-phase arrest and apoptosis in pancreatic cancer cell lines; also inhibits the activation of Notch-1 and Jagged-1 in vitro and in vivo.

Preparing Stock Solutions

The following data is based on the product molecular weight 573.7. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 1.74 mL 8.72 mL 17.43 mL
5 mM 0.35 mL 1.74 mL 3.49 mL
10 mM 0.17 mL 0.87 mL 1.74 mL
50 mM 0.03 mL 0.17 mL 0.35 mL
