Fig. 3From: Oral vaccination with recombinant Lactobacillus casei expressing Aha1 fused with CTB as an adjuvant against Aeromonas veronii in common carp (Cyprinus carpio)Expression of Aha1 protein from recombinant L. casei cell lysate by Western blot analysis and expression of Aha1 protein on recombinant cell surface by fluorescence microscopy analysis. A Identification of the proteins of expressed by the recombinant strains pPG-Aha1/Lc CC16 and pPG-Aha1-CTB/Lc CC16 by Western blotting with mouse anti-Aha1. MW indicates the molecular mass markers (kDa). 1: The expression of induced pPG-Aha1/Lc CC16; 2: The expression of induced pPG-Aha1-CTB/Lc CC16; 3: The expression of induced pPG/Lc CC16. B fluorescence microscopy analysis of Aha1 protein expression on recombinant cell surface. pPG-Aha1/Lc CC16 (left), pPG-Aha1-CTB/Lc CC16 (middle) and pPG/Lc CC16 (right), magnification: × 1000. There was green fluorescence on the surface of pPG-Aha1/Lc CC16 and pPG-Aha1-CTB/Lc CC16, respectively. As controls, no immunofluorescence reaction on the pPG/Lc CC16 cell surfaceBack to article page
