Assay: Kinase assays: Kinase assays were performed in 96 well microtiter plates that were coated overnight with 30.mu.g of poly-Glu-Tyr (4:1) in 10 mM Phosphate Buffered Saline (PBS), pH 7.2-7.4. The plates were incubated with 1% BSA and then washed four times with PBS prior to starting the reaction. Reactions were carried out in 120.mu.L reaction volumes containing 3.6.mu.M ATP in kinase buffer (50 mM Hepes buffer pH 7.4, 20 mM MgCl.sub.2, 0.1 mM MnCl.sub.2 and 0.2 mM Na.sub.3 VO.sub.4). Test compounds were reconstituted in 100% DMSO and added to the reaction to give a final DMSO concentration of 5%. Reactions were initiated by the addition 0.5 ng of purified protein. Following a ten minute incubation at 25.degree. C., the reactions were washed four times with PBS containing 0.05% Tween-20. 100.mu.l of a monoclonal anti-phosphotyrosine antibody-peroxidase conjugate was diluted 1:10000 in PBS-Tween-20 and added to the wells for 30 minutes.

The reaction was started by addition of enzyme, and the progress of the reaction was followed by measuring fluorescence with an excitation wavelength of 480 nm and an emission wavelength of 520 nm. Ten measurements were taken every 5-10 min, and the intensity of fluorescence was regressed against time in order to derive velocities of reaction in all 96 wells.
