| | Enzymatic Activity of Wee1 |
| Description: | In the present disclosure, Wee1 enzyme catalysis assay was carried out using the ATP-Glo Max kinase luminescence detection kit (Promega). Kinase activity was assessed by quantitative detection of the amount of ATP retained in the solution following the kinase reaction. The luminescent signal in the assay is proportional to the amount of ATP and inversely proportional to the kinase activity. The concentration of the compound in the assay ranged from 0.5 nM to 30 μM. The compound was dissolved in 10% DMSO, and 5 μL of the solution was added to 50 μL of the reaction, and the concentration of DMSO in the final reaction was 1%. The reaction was carried out at 30° C. for 50 minutes. 40 mM trishydroxymetyl aminomethane, pH 7.4, 10 mM MgCl2, 0.1 mg/ml BSA, 2 mM DTT, 0.1 mg/ml Poly (Lys, Tyr) substrate, 10 μM ATP and Wee1 were contained in the reaction mixture. After the enzymatic reaction, 50 μL of ATP-Glo Max kinase luminescence detection assay solution (Promega) was added and incubated for 15 minutes at room temperature. The luminescent signal was measured using a microplate reader. In some assays, a known Wee1 inhibitor was added as a positive control. Luminance data was analyzed using Graphpad software. |
