Apoptosis inducer in several tumor cell lines including T47D cells. Activates caspases (EC50 values are 0.78 - 1.64 μM) and competitively inhibits antiapoptotic Bcl-2 family proteins (IC50 values are 1.47, 1.21, 2.02, 0.66, 1.06 and 0.79 μM for Bcl-XL, Bcl-2, Bcl-W, Bcl-B, Bfl-1 and Mcl-1 respectively). Reverses gefitinib-resistance in mice bearing tumors with EGFR-T790M mutation. Also blocks Kir2.1 channels (EC50 ≤ 100 nM).

Preparing Stock Solutions
The following data is based on the product molecular weight 628.75. 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.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||1.59 mL||7.95 mL||15.9 mL|
|5 mM||0.32 mL||1.59 mL||3.18 mL|
|10 mM||0.16 mL||0.8 mL||1.59 mL|
|50 mM||0.03 mL||0.16 mL||0.32 mL|

Programmed Cell Death Poster
There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
