The interaction of NF‐κB2/p58 with other NF‐κB subunits. The cell lysates were prepared from 293T cells transfected either with pCMV‐HA‐p100, pCMV‐HA‐p52, or pCMV‐HA‐p58, and they were immunoprecipitated with anti‐hemagglutinin(HA) antibody. The total cell lysates (Input) and immunoprecipitates (HA IP) were then characterized by a Western blot analysis by using either anti‐RelB, anti‐p65, or anti‐HA antibody.
