Figure 3From: Recombinant porcine rotavirus VP4 and VP4-LTB expressed in Lactobacillus casei induced mucosal and systemic antibody responses in miceImmunofluorescence analysis. Wild-type L. casei 393 was induced by xylose, the result of immunofluorescence was negative, and the cells were dyed red by Evans blue (A). When pPG612.1-VP4 and pPG612.1-VP4-LTB were induced by xylose, there were green-yellow fluorescence reaction on the surface of the cells (B, C).Back to article page
