MC1061 F- Electrocompetent Cells. A non-amber suppressor strain, identical to SS320 except that it lacks the F′episome. Highly efficient (≥4 × 1010 cfu/µg) electrocompetent cells for general cloning or Phage Display. Note that as an F- strain, it cannot be used for re-infection by filamentous phage. This strain not included in the sample kit.
