Tyr525/526 represent the phosphorylation sites in human Syk, while Tyr519/520 are the equivalent phosphorylation sites in mouse Syk. For immunoblotting the membrane should be incubated with antibody diluted in 5% BSA, 1X TBS, 0.1% Tween®-20 detergent at 4°C overnight with gentle shaking. Antibody should be titrated for optimal results in individual systems.
