Detection of human CoCoA by Immunoprecipitation in whole cell lysate from MCF7 cells (1 mg, 20% of immunoprecipitate loaded/lane), using ab70563 at 3 µg/mg of lysate (lane 1). CoCoA was also immunoprecipitated using another CoCoA antibody (ab70564) which recognizes a downstream epitope (lane 2). Lane 3: Control IgG immunoprecipitate. Subsequent blotting of immunoprecipitate for the detection of CoCoA was performed using 1µg/ml of the other antibody (ab70564) and 50µg of lysate. Detection was by chemiluminescence with an exposure time of 30 seconds.
