[0019] 1. Establishment of screening method for TrkB kinase inhibitors
[0020] (1) Experimental materials
[0021] TrkB kinase detection kit (Cisbio, France), TrkB kinase (Invitrogen, USA), ATP (Shengxing, China), staurosporine (Beyond, China), 384 low-volume white plate (Coming, USA), pipette tip ( Axygen, USA).
[0022] (2) Experimental steps
[0023] 1) Carry out TrkB kinase concentration gradient, incubation time, substrate concentration, ATP concentration experiments, see Figure 1-4 .
[0024] 2) Accurately weigh the compound to be tested, add DMSO solvent to form a mother solution, and then use the detection buffer to prepare the solution of the compound to be tested to the required concentration. The initial screening concentration is about 1×10 -3 mol / L.
[0025] 3) Add 2 μl of TrkB kinase solution, 2 μl of substrate solution, 4 μl of buffer or compound to be screened, and 2 μl of ATP into each well of the reaction vessel. React at room temperature for 1 hour. ...
