Flow cytometry examination for the presence of CEACAM1, 5 and 6 expression. CEACAM expression in AGS (a), HN (b), CAL-27 (c) and BHY (d) cells was demonstrated for non-infected cells during log phase growth (thin curves) and when in tight confluence (bold curves), stained with monoclonal antibodies specific for CEACAM1 (left), CEACAM5 (middle) and CEACAM6 (right), and with isotype-matched control antibodies (grey filled curves) followed by FITC-conjugated secondary antibody. The presented results are representative for three independent experiments
