Figure Lengend Snippet: Immunofluorescence microscopic detection of Stx-binding GSLs in MDCK II (A) and Vero-B4 cells (B). The epithelial cell lines were grown in chamber slides and incubated with Stx1a, Stx2a, or Stx2e as indicated. Bound Stx1a and Stx2 subtypes were detected with anti-Stx1 and anti-Stx2 antibody, respectively, in conjunction with Alexa Fluor 488®-labeled secondary antibodies. Fluorescence imaging was performed for the apical cell surface (apical plane), on intracellular level (midplane) and at the basal cell surface (basal plane). The immunofluorescence micrographs merged with the DAPI stains of the nuclear DNA are shown.
Article Snippet: After one more washing step with PBS, the Stx1a-exposed slides were incubated with monoclonal mouse IgG anti-Stx1 antibody (clone VT109/4-E9B) and those exposed to Stx2a and Stx2e with monoclonal mouse IgG anti-Stx2 antibody (clone VT135/6-B9, both from Sifin GmbH, Berlin, Germany) in 1:500 dilution with 1% BSA at 4°C overnight.
