2D-E profile of M. pneumoniae M129 total extract and immunoblots. 2D-E profile of total extracts (A) and immunoblots probed with 10 serum samples from RTI patients infected with M. pneumoniae (B) or 10 serum samples from healthy blood donors (C). Labelled spots represent the M. pneumoniae antigenic proteins that were detected with serum samples from the study population. The gel spots were encoded using a protein number (Table 1), which was assigned based on their similar locations on different gels/membranes.
