Figure 4.
Global tyrosine phosphorylation analysis of Src and mutants. SYF cells were transiently transfected with c-Src or mutants. Cells were harvested 40 h post-transfection, and lysates (50 μg) were separated via 10% SDS–PAGE and transferred onto a PVDF membrane. The membrane was probed with anti-pTyr antibody and reprobed with anti-Flag antibody to check expression. The membrane was probed with anti-tubulin antibody as a loading control. Vector represents SYF cells transfected with empty vector alone. The figure is representative of three separate experiments.
