Figure 2

Serpin concentration and localization in extracts of B. longum NCC 2705, its serpin knock-out counterpart (NCC 9035) and the constitutively producing (NCC 2705 harboring pMDY25) recombinant strain. Means and standard deviations are depicted. Black bars represent cytoplasmic fractions, dark grey bars represent cell-wall associated fractions and light grey represent supernatant fractions (i.e. excreted protein). Serpin amounts are reported in picograms (pg) per mg of total protein.
