生物学描述Widely used as a cell-permeable, reversible, competitive protein kinase C inhibitor. Also potently inhibits wide range of kinases inlcuding RSK1, RSK2, PRK2, PKCα, PKD1, MSK1, GSK3β, CDK2-cyclin A and PIM3, as well as PKCα.
Also available in simple stock solutions (ab146723) - add 1 ml of water to get an exact, ready-to-use concentration.
存放说明Store at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
溶解度概述Soluble in water to 100 mM, DMSO to 100 mM and in ethanol to 5 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.
1.5 x 10e7 THP-1 cells were incubated with 100 nM GF 109203X (ab144264) or Ro 31-8220 mesylate (ab120374) for 30 minutes prior to activation with 10 µg x mL-1 PMA (Sigma) for 4 hours. Control cells were left without inhibitors or PMA. Cells were lysed in 1 mL of lysis buffer, and 30 µL were tested for PKC activity (duplicates; +/- SD).
