Ole1p-Myc and Ole1p-FLAG association revealed by co-immunoprecipitation analysis. A, yeast extracts from strain YPH499 expressing combinations of Ole1p-Myc and Ole1p-FLAG, as indicated, were subject to immunoprecipitation (IP) with anti-FLAG antibody or lacking the addition of antibody as negative control (NC). Samples were separated by SDS-PAGE, immunoblotted, and visualized with the use of anti-Myc antibodies. The bands corresponding to Myc- and FLAG-tagged Ole1p are indicated. B, same as A except that immunoprecipitation was performed with anti-Myc antibodies and immunoblotting was performed with anti-FLAG antibodies.
