  • B834 is parental strain for BL21 (1)
  • Protease-deficient hosts are methionine auxotrophs
  • Allows high specific-activity labeling of target proteins with methionine and selenomethionine for crystallography
  • pLysS strains express T7 lysozyme
  • Suppresses basal expression of T7 RNA polymerase prior to induction, thus stabilizing pET recombinants encoding target proteins that affect cell growth and viability
