A cell-permeable, selective inhibitor of casein kinase-2 (CK2) (IC50 = 0.9 and 1.6 μM for rat liver and human recombinant CK2 respectively). Exhibits modest discrimination between CK2 subunits, with Ki values ranging from 80 nM to 210 nM. Acts in an ATP/GTP-competitive manner and displays one to two orders of magnitude selectivity over a panel of 33 protein kinases.

Preparing Stock Solutions
The following data is based on the product molecular weight 434.71. 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||2.3 mL||11.5 mL||23 mL|
|5 mM||0.46 mL||2.3 mL||4.6 mL|
|10 mM||0.23 mL||1.15 mL||2.3 mL|
|50 mM||0.05 mL||0.23 mL||0.46 mL|
