[1632] Procedures and Methods:

[1633] Gradient Dilution of Compounds:

[1634] The test compound was dissolved with DMSO to be of 1 mM as a stock solution. Such a stock solution was diluted with DMSO by 10-fold, thereby obtaining an initial solution in a concentration of 1 μM which was added into wells at the second column in a plate. 20 μL DMSO was added to other wells using Bravo. Then, 10 μL of the initial solution was transferred from wells at the second column to wells at the third column, followed by mixing obtained solution in the wells at the third column, thereby obtain a first diluted solution in a concentration of 1/3 μM. Subsequently, 10 μL of the first diluted solution was further transferred from wells at the third column to wells at the fourth column, followed by mixing obtained solution in the wells at the fourth column, thereby obtain a second diluted solution in a concentration of 1/9 μM. Such a three-fold serial dilution was performed 10 times, with 11 solutions in series diluted concentrations and a final diluted solution in a concentration of 0.017 nM obtained.

[1635] All diluted solutions were further diluted by 25-fold with ultrapure water, thus obtain test solutions, which were equilibrated at r.t. for 30 min before use.

[1636] Enzymatic Reaction:

[1637] To 2.5 μL of test solution, which was pipetted into each well of Assay plate using Bravo, 5 μL kinase mixture was added using the multi-channel pipettor. The mixture was centrifuged at 1000 rpm for 20 s, followed by incubation at 23° C. for 30 min. The reaction was initiated by 2.5 μL ATP mixture which was pipetted into the wells by Multidrop.

[1638] The reaction mixture of BTK kinase (10 μL) included 1.0 nM BTK, 1 μM biotin-TK1 peptide and 20 μM ATP. The reaction buffer included 50 mM Hepes (pH7.5), 10 mM MgCl.sub.2 and 0.01 mM NaV.sub.3VO.sub.4. The kinase mixture was reacted in incubator at 23° C. for 90 mim.

[1639] Completion of Reaction:

[1640] The reaction was stopped by adding 10 μL Detection Reagent to each well of Assay plate, and the plate was left in incubator at 23° C. for 1 h before read on Envision.
