(B) Immuno-blot analysis quantifying σfrom EGD-e at different growth phases. Proteins were isolated from cultures of EGD-e grown for 3 h (lane 1), 4 h (lane 2), 8 h (lane 3) and 16 h (lane 4) in BHI at 37°C and σwas detected using rabbit polyclonal anti-serum produced against COL σ. The Δdeletion mutant (lane 5) was used as negative control and COL (lane 6) was used as positive control for specific binding of the antibody. Molecular masses (in kilodaltons) of prestained SDS-PAGE standard marker (Bio-Rad) are indicated on the left and σis marked on the right
