## Endpoint to Predict
- Endpoint scope: assay
- Measurement type: IC50
- Label type: continuous
- Binary semantics: pchembl
- Assay description: Z′-LYTE Biochemical Aassay: Z′-LYTE® Assay Conditions: Test Compounds: The Test Compounds are screened in 1% DMSO (final) in the well. For 10 point titrations, 3-fold serial dilutions are conducted from the starting concentration. Peptide/Kinase Mixtures: All Peptide/Kinase Mixtures are diluted to a 2× working concentration in the appropriate Kinase Buffer. ATP Solution: All ATP Solutions are diluted to a 4× working concentration in Kinase Buffer (50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA). ATP Km apparent is previously determined using a Z′-LYTE® assay. Development Reagent Solution: The Development Reagent is diluted in Development Buffer. 10× Novel PKC Lipid Mix: 2 mg/mL Phosphatidyl Serine, 0.2 mg/mL DAG in 20 mM HEPES, pH 7.4, 0.3% CHAPS. For 5 mL 10× Novel PKC Lipid Mix: 1. Add 10 mgs Phosphatidyl Serine (Avanti Polar Lipids Part #8400032C or 840039C) and 1 mg DAG (Avanti Polar Lipids Part #800811C) to a glass tube. 2. Remove the chloroform from lipid mixture by evaporating to a clear, thin film under a stream of nitrogen. Continuous rotation of the tube, at an angle to ensure maximum surface area of the lipid solution, will promote the thinnest film. 3. Add 5 mLs resuspension buffer, 20 mM HEPES, 0.3% CHAPS, pH 7.4, to the dried lipid mix 4. Heat gently to 50-60° C. for 1-2 minutes and vortex in short intervals until the lipids are dissolved to a clear or slightly hazy solution. The lipids are typically in solution after 2-3 heat/vortex cycles. 5. Cool to room temperature, aliquot into single use volumes and store at −20° C. Assay Protocol: Bar-coded Corning, low volume NBS, black 384-well plate (Corning Cat. #4514) 1. 2.5 μL 4× Test Compound or 100 nL 100× plus 2.4 μL kinase buffer. 2. 5 μL 2× Peptide/Kinase Mixture. 3. 2.5 μL 4× ATP Solution. 4. 30-second plate shake. 5. 60-minute Kinase Reaction incubation at room temperature. 6. 5 μL Development Reagent Solution. 7. 30-second plate shake. 8. 60-minute Development Reaction incubation at room temperature. 9. Read on fluorescence plate reader and analyze the data. In a typical experiment, each data point uses 100 nL 100× test compound in 100% DMSO. Commonly, 100 nL of a 10 μM solution of test compound is used for each experiment, which is equivalent to 1 picomole of test compound. Accordingly, a 10 μM single-point assay uses 100 picomoles of test compound, and a 10-point titration uses about 200 picomoles of test compound 100 picomoles for the initial test and another 100 picomoles for the serial dilution.
