Published customer image: . Mouse anti Pig Endothelial Cells antibody, clone MIL11 used for the identification of porcine jujenal vasculature by immunofluorescence. Image caption: . Colonisation expands IgM and IgA-producing mucosal plasma cells. (A) IgA staining in jejunal mucosa from a GF pig and (B) a colonised pig at 21 days of age. Sections were stained with antibodies to IgA (red) and capillary endothelium (MIL11; in blue). In both (A) and (B), (i) shows the two-colour image; (ii) shows the original greyscale image for the red channel (IgA); (iii) shows the original greyscale image for the blue channel (endothelium). Scale bar represents 10 µm. (C) IgM staining in jejunal mucosa from a GF pig and (D) a colonised pig at 21 days of age. Sections were stained with antibodies to IgM (red). Scale bar represents 10 um. (E) Area of IgM and (F) IgA staining in jejunal sections from piglets at birth (open diamonds) and GF piglets (open squares) and colonised piglets (black squares) at 5 and 21days of age (see Table 1 for numbers of piglets in each experiment). * p<0.01. doi:10.1371/journal.pone.0033707.g001.
