|Description||Bisindolylmaleimide I (GF109203X) is a potent PKC inhibitor with IC50 of 20 nM, 17 nM, 16 nM, and 20 nM for PKCα, PKCβI, PKCβII, and PKCγ in cell-free assays, respectively, showing more than 3000-fold selectivity for PKC as compared to EGFR, PDGFR and insulin receptor.|
|Features||Greater selectivity than PKC inhibitor staurosporine. GF109203X is a chemical probe for studying PKC signal transduction pathways. Potential for use in a variety of cancers.|
GF109203X, as an ATP-competitive PKC inhibitor, prevents platelet aggregation induced by stimuli that activate PKC, and has the potential as a tool for studying the involvement of PKC in signal transduction pathways.  GF 109203X produces reversal activity on P-glycoprotein and MRP -mediated multidrug resistance.   PKC inhibition by GF109203X significantly reduces carbachol-stimulated ERK1/2 activation and the subsequent proliferation of SNU-407 colon cancer cells. 
|In vivo||GF109203X (10 μg/mouse, i.pl.) dose-dependently inhibits BK-induced mechanical allodynia in Wistar rats. |
Assay of protein kinase C:Protein kinase C is arrayed by measuring 32PI transferred from [gamma-32PI] ATP to lysine-rich histone type Ill-s. The reaction mixture (80 μL) contained 50 mM Tris-HCI. pH 7.4, 100 μM CaCl2, 10 mM MgCI2, 37.5 μL/mL histone type Ill-s, 10 μM [gamma-32PI] ATP (1250 cpm/pmol), 31 μM bovine brain phosphatidylserine and 0.5 μM 1,2 sn-dioleylglycerol. Fifteen μL of purified PKC (final concentration in assay 0.38 μg/mL) is added to the incubation mixture. After 10 min at 30°C, the reaction is stopped by addition of 30 μL of casein 30 mg/mL and 0.9 ml of 12% trichloroacetic acid. The acid precipitable material is collected by centrifugation, dissolved in 1N NaOH (100μL) and precipitated again with 1 ml of 12% trichloroacetic acid. The pellet is dissolved in 1N NaOH (100μL) and 32P incorporation is measured by scintillation counting in Aquasol.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
