Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO to 25 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.

2D chemical structure image of ab144264, GF 109203X (Bisindolylmaleimide i), PKC inhibitor
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).
To our knowledge, customised protocols are not required for this product. Please try the standard protocols listed below and let us know how you get on.
