GSH peroxidase activity in recombinant protein and in lysates of MPMVEC expressing WT or Ser-32 mutant Prdx6 delivered by lentivirus infection
Prdx6 null MPMVEC were infected with lentivirus expressing wild type or mutant human Prdx6 or vector alone. Values are mean ± S.E. for n = 3 independent experiments.
