Prokaryotic

E. coli NEB 5a

• A DH5-alpha derivitive supplied by New England Biolabs
• Used for general cloning including Bgal selection.
• Electrocompetent cells are kept in the -80°C Freezer in Dr. Demirci's lab.
• Ask Mike

E. coli DB3.1

• These clones are subject to ccdb lethality
• Plasmids with the ccdb gene surrounding the MCS are used to select for inserts
  • DB3.1 cells with non insert plasmids will die
