  10. KAH170/pSB31-5, seq_pSB31 rev: failed (ns)
  11. SP1AB 2/3mut-1, P0001: discrepancy at bp 230 (A -> G); failed to mutate PstI #1; mutated PstI #2 (keep this clone)
  12. SP1AB 2/3mut-1, P0002: discrepancy at bp 1141 (A -> G); mutated PstI #3
  13. SP1AB 2/3mut-2, P0001: discrepancy at bp 230 (A -> G); failed to mutate PstI #1; mutated PstI #2
  14. SP1AB 2/3mut-2, P0002: discrepancy at bp 1141 (A -> G); mutated PstI #3
  15. SP1AB 2/3mut-3, P0001: discrepancy at bp 230 (A -> G); failed to mutate PstI #1; mutated PstI #2
  16. SP1AB 2/3mut-3, P0002: discrepancy at bp 1141 (A -> G); mutated PstI #3
  17. SP1AB 2/3mut-4, P0001: n/d
  18. SP1AB 2/3mut-4, P0002: n/d
  19. SP1AB 2/3mut-5, P0001: n/d

  22. SP1AB 2/3mut-6, P0002: n/d

--> Pc-TF/pSB31: Success! Got all three clones for ES cell transfection experiment. Maxi prep and send to Manching. Reverse primer failed (discard/ design new primer).
--> SP1AB mutagenesis: U2OS seems to have two missense mutations in the SP1AB activation domain (bp 230: Gln -> Arg; bp 1141: Ser -> Gly). Keep clone #1 for mutation of PstI #1 (design new longer primer).
