Fig 2. Activation of NF-κB by different strains of E. faecalis.

IEC-6 cells were treated with 10¹⁰ cfu/ml each strain of E. faecalis and activation of the NF-κB pathway was determined by western blotting for IκBα. β-actin reprobes are included to demonstrate lane load. Representative blots of 3 independent experiments are shown.
