## Endpoint to Predict
- Endpoint scope: assay
- Measurement type: IC50
- Label type: continuous
- Binary semantics: pchembl
- Assay description: FBXL10 Assay: The ability of test compounds to inhibit the activity of FBXL10 was determined in 384-well plate format under the following reaction conditions: 0.3 nM FBXL10, 30 nM H3K36me2-biotin labeled peptide (Anaspec cat #64442), 0.2 μM alpha-ketoglutaric acid in assay buffer of 50 mM HEPES, pH7.3, 0.01% Brij35, 0.5 mM TCEP, 0.2 mg/ml BSA, 50 μM sodium L-ascorbate, and 5 μM ammonium iron(II) sulfate. Reaction product was determined quantitatively by AlphaScreen detection after the addition of detection reagents anti-H3K36me1 antibody, AlphaScreen® Streptavidin-coated Donor beads, and AlphaScreen® Protein A Acceptor beads in 50 mM HEPES, pH7.3, 10 mM NaCl, 0.01% Brij35, 5 mM EDTA, 2 mg/ml BSA to final 10 μg/ml beads.The assay reaction was initiated by the following: 3 μl of the mixture of 90 nM H3K36me2-biotin labeled peptide and 0.6 μM alpha-ketoglutaric acid with 3 μl of 11-point serial diluted inhibitor in 3% DMSO were added to each well of 384 well Proxiplate (Perkin Elmer), followed by the addition of 3 μl of 0.9 nM FBXL10 to initiate the reaction. The reaction mixture was incubated at room temperature for 30 minutes, and terminated by the addition of 3 μl of 50 mM HEPES, pH7.3, 10 mM NaCl, 0.01% Brij35, 5 mM EDTA, 2 mg/ml BSA containing appropriate dilution of anti H3K36me1 antibody. Plates were incubated at room temperature for 40 minutes, followed by addition of 3 μl of 50 μg/ml AlphaScreen® Streptavidin-coated Donor beads and AlphaScreen® Protein A Acceptor beads in 50 mM HEPES, pH7.3, 10 mM NaCl, 0.01% Brij35, 5 mM EDTA, 2 mg/ml BSA. Plates were read by EnVisionMultilabel Reader in AlphaScreen mode after a minimum of 2 hour or up to overnight incubation at room temperature. The AlphaScreen signal for each well was used to determine inhibition constant (IC50).
