P-FPMI-225 - P-FPMI-225

Mid-exponential phase broth cultures of bacteria (Salmonella enteritidis (subtype Typhimurium)) were added to the apical surface

of polarized cells at an MOI of 50 viable bacteria per cell.

16HBE14O- epithelial cells and bacteria were incubated together for 1h in complete MEM.

The supernatants containing the bacteria were then replaced by fresh sterile medium and cells were incubated for a

further 3 hours, after which they were lysed with the RLT lysis buffer supplemented with β-mercaptoethanol

(RNeasy Mini kit, with RNase-Free DNase treatment (Qiagen, Hilden, Germany)).
