Potent, selective casein kinase 1ε (CK1ε) and CK1δ inhibitor
Biological descriptionPotent, selective casein kinase 1ε (CK1ε) and CK1δ inhibitor (IC50 values are 7.7 and 14 nM for CK1ε and CK1δ, respectively). Shows >300-fold selectivity over CK2 and selectivity over more than 40 other kinases. Alters circadian rhythms in vivo.
Also available in simple stock solutions (ab146728) - add 1 ml of water to get an exact, ready-to-use concentration.
Chemical name4-[1-Cyclohexyl-4-(4-fluorophenyl)-1H-imidazol-5-yl]-2-pyrimidinamine dihydrochloride
Storage instructionsStore at Room Temperature. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in water to 100 mM and in DMSO to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
