|Description:||KU-55933 is a cell-permeable ATP-competitive inhibitor of ATM (IC50 = 13 nM; Ki = 2.2 nM) with selectivity over other PIKK family kinases (IC50 = 2.5, 9.3, 16.6 μM for DNAPK, mTOR, PI 3-K, respectively; IC50 > 100 μM for PI 4-K and ATR).|
|Stability and Solubility Advice:|| Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials at -20°C or below and used within 1 month.
