DB3.1 resistance - (Mar/14/2007 )

Does anyone know if DB3.1 competent cells resist either streptomycine or ampiciline? Thanks in advance Mariana


DB3.1 cells are used to grow plasmids containing ccDB gene. I dont think they have resistance to antibiotics.

They are like any other cells used for transformation.


pUC19 is provided as a control plasmid, so I'm guessing that these cells will not be resistant to ampicillin, or the pUC19 would be useless.


DB3.1 is streptomycin resistant, but otherwise unmarked. See
