hERG1a and hERG1b coimmunoprecipitate when hERG1b expression is induced. Cells were treated for 24 hours with increasing concentrations of DOX and probed for hERG expression and interaction between hERG1a and 1b subunits. Western blot showing expression of hERG1a and the induction of hERG1b using 50 and 100 ng/ml of DOX (Input). Coimmunoprecipitation of hERG1a with hERG1b was revealed by probing for both subunits using a pan-hERG antibody in cells treated or not with DOX (Co-IP).
