PP2A Immunoprecipitation Phosphatase Assay Kit (Millipore) was used for immunoprecipitation and enzyme activity quantification. One reaction contained PP2A from sonicated cell lysate (aliquot corresponding to 2.5×105 cells). Released phosphate amounts were measured by a malachite green colorimetric assay. Experiments were performed 4 times with 2 technical replicates.
