Depositor Comments

The 1.1-kb XbaI-EcoRI fragment from pJW168 (PMID 9858684) was cloned between the XbaI and EcoRI sites of pCM62 (Addgene plasmid 45826) to generate the tetracycline-resistance conferring cre expression plasmid.
Used with allelic exhange vectors--Addgene plasmids 46012 or 46013--to generate unmarked mutant strains in a broad bacterial host range.
