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.

• TG1 Electrocompetent Cells. An amber suppressor strain (supE) prepared as highly efficient (≥4 × 10¹⁰ cfu/µg) electrocompetent cells for phage display library screening. These cells are used for phage display and protein expression.

• SS320 Electrocompetent Cells. A non-amber suppressor strain (sometimes called MC1061F') prepared as highly efficient (≥4 × 10¹⁰ cfu/µg) electrocompetent cells for phage display library screening. These cells have the highest available transformation efficiency of any strain used for phage display.
• ER2738 Electrocompetent Cells. An amber suppressor strain (glnV) prepared as highly efficient (≥2 × 10¹⁰ cfu/µg) electrocompetent cells for phage display library screening. This strain is recommended for use with New England Biolab's Ph.D.™ Phage Display Kits.
