    Product Information

    Product Usage Information

    Bisindolylmaleimide I is supplied as 500 μg powder. Store at or below -20ºC. Before use, dissolve powder in 0.28 ml DMSO to make a 4 mM bisindolylmaleimide I stock solution. For working concentrations of 2 μM-4 μM, dilute DMSO stock 1:2000 to 1:1000. Treat cells with the desired concentration for 30 minutes.

    Storage

    Store lyophilized or in solution at -20ºC, desiccated. Protect from light. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

    Background

    Bisindolylmaleimide I (BIS), also known as GF-109203X, is a potent inhibitor of PKC (1,2). In vitro, the IC50 of BIS is 10-20 nM for PKCα/β/γ and 100-200 nM for PKCδ/ε isoforms. The in vitro IC50 for PKCζ is approximately 6 μM, indicating that BIS is a very weak inhibitor for this isoform. In in vivo cellular assays, the IC50 of BIS for PKC is 0.2-2 μM (1,3).
