Are any of you using an E. Coli with a lac mutation that deletes all the lacZ 
coding region while leaving the repressor and its promoter ? I don't want

Episomes or host chromosome deletions are both suitable, as well as lac IQ 
You might want to contact the E. Coli bank at the Department of Human Genetics
at Yale Med. School.
