Western blot analysis of extracts from PC-3 cells and wild-type (wt) and Nf2 knockout (-/-) mouse embryonic fibroblasts (MEFs), untreated (-) or λ phosphatase-treated (+), using Phospho-Merlin (Ser518) (D5A4I) Rabbit mAb (upper), Merlin (D3S3W) Rabbit mAb #12888 (middle), or Ezrin/Radixin/Moesin Antibody #3142 (lower). (MEF wt and MEF Nf2 (-/-) cells were kindly provided by Dr. Andrea McClatchey, MGH Cancer Center and Harvard Medical School, Charlestown MA).
Immunoprecipitation of Phospho-Merlin (Ser518) protein from PC-3 cell extracts using Rabbit (DA1E) mAb IgG XP ® Isotype Control #3900 (lane 2) or Phospho-Merlin (Ser518) (D5A4I) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot analysis was performed using Phospho-Merlin (Ser518) (D5A4I) Rabbit mAb.
