Co-immunoprecipitation results from two ALK+ALCL cell lines, SUP-M2 and Karpas299. The monoclonal and polyclonal anti-ALK immunocomplexes were resolved by SDS-polyacrylamide gel electrophoresis, transferred to a nitrocellulose membrane and used for Western blot analysis. Western blot analysis demonstrated the physically association of NPM-ALK (A), Hsp90 (B), Stat3 (C), MSH2 (D), Nup98 (E), Importin 8 (F), Stim1 (G), 82Fip (H), and MCM6 (I).
