Construction of pNZ2103-NA and expression of NA protein on L.lactis . (A) A schematic diagram of constitutive plasmid pNZ2103-NA. (B) Western blot analysis of recombinant L.lactis/pNZ2103-NA expression. Lane 1: negative control L.lactis/pNZ2103; Lane 2: MagicMark™ XP Western Protein Standard; Lane 3: L.lactis/pNZ2103-NA. A specific protein band of around 54 kDa corresponding to NA was detected using anti-NA monoclonal antibody.
