Co-immunoprecipitation assay of protein–protein interaction with MSX1. (Upper panels) Western blot analyses of whole cell lysates from COS7 cells cotransfected with Myc-tagged PAX9 proteins and FLAG-tagged MSX1. (Lower panels) Western blot analyses of proteins pulled down with α-FLAG antibody from whole cell lysates. Immunoprecipitated MSX1 was detected with the α-FLAG antibody and co-immunoprecipitated wild-type and missense mutant PAX9 proteins with antibody against the C-terminal transactivation domain of PAX9.
