OverviewNovaBlue is a K-12 strain ideally suited as an initial cloning host due to its high transformation efficiency, blue/white screening capability (with appropriate plasmids) and recA endA mutations, which result in high yields of excellent quality plasmid DNA. The DE3 lysogen of NovaBlue is potentially useful as a stringent host due to the presence of the lacIq repressor encoded by the F episome. Blue/white screening is not possible with NovaBlue(DE3) due to the presence of the lacZ α-peptide coding sequences in the lysogenic phage.
