Western blot analyses of proteins of HHY212d strains harboring both recombinant plasmids, pBM-TIF51A and p414GAL1-heIF5A (A) and of HHY212s strains expressing only the human eIF5A proteins (B). All the strains in A were cultured in SGal,-His,-Leu,-Trp,-Ura and those in B, cultured in SGal,-His,-Leu,-Trp. The experiments were repeated two times with virtually the same results: a typical experiment is shown.
