| Description: | CDK5 (p25): IC50 values of compounds against CDK5 (p25) were determined by Z′-LYTE™. These screening assays were performed at Invitrogen Life Technologies (Grand Island, N.Y.) on a low volume NBS, black 384-well plate (#4514, Corning). 0.1 μL of 100× test compound in 100% DMSO (at specific solutions) were mixed with 2.4 μL of Kinase Buffer (50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA), 5 μL of 2× Kinase (0.18-2 ng CDK5/p25)/Peptide (2 μM Ser/Thr 12), and 2.5 μL of 4×ATP solution (17 μM). The plates were shaken for 30 seconds, and incubated for 60 minutes at room temperature. Development Reagent Solution (5 μL of 1:4096 dilution) was added to the plates followed with another 30-second plate shake and the plates were further incubated at room temperature for one hour. The plates were read on fluorescence plate reader with Dual emission at 445 nm and 520 nm. |
