ab197620 was shown to recognize Bmi1 in wild-type HAP1 cells as signal was lost at the expected MW in COMMD3-BMI1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and COMMD3-BMI1 knockout samples were subjected to SDS-PAGE. ab197620 and ab130007 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. The loading control was imaged using the Licor Odyssey CLx prior to blots being developed with ECL technique.
