Analysis of Receptor Tyr Kinases (RTK) activation in human breast cancer MDA-MB-231 cells. A. Cells were treated with medium alone or added SLO (10 units/ml) or EGF (50 ng/ml) and extracts analyzed as described in Materials and Methods. Data are representative of independent replicates for each condition. B. Cells were pre-treated with or without SLO, then with peroxyvanadate (PV) and processed to analyze RTK activation.
