===Notes===
Useful host for primary transformation.  Transforms very well by the CaCl<sub>2</sub> method (10<sup>7</sup>/µg).  There is no Type I restriction; incoming DNA receives the E. coli K modification.<br />
Lysogenized with λ wild type.<br />
As this strain is deleted for the lacI repressor gene, it is not a suitable host for plasmids carrying the lac promoter or derivatives thereof, such as ''tac'', ''trc'', ''N25/O2'' … promoters. In the absence of repression, continuous transcription from the lac promoter is likely to result in plasmid instability.<br />
