Inducible HipB antitoxin under the control of lac promoter
HipB is the antitoxin of the HipAB toxin-antitoxin (TA) module. HipB neutralizes the toxin effect of HipA due to protein-protein interactions.

Functional characterization
As HipB neutralizes the induction of persistency caused by HipA7 in this strain, we induced our strain with IPTG at different concentrations and evaluate the persisters frequencies implementing an original protocol for persister cells isolation based on lysis (S. Cañas et al., Manuscript in preparation). For
For this experiment with used the Escherichia coli K12 TH1269 strain (hipA7) which is a high persistence mutant. We evaluated the persistence frequencies of untransformed TH1269 strain and Escherichia coli K12 MG1655 (wild type) as a control. This experiment was made in LB medium supplemented with Ampicillin (100 ug/mL) for insuring plasmid maintenance.
