Recognition of pneumococcal iga gene product by affinity-purified anti-epiA antibodies. Western blot analysis on whole cell lysates from S. pneumoniae R6 (lanes 1 and 4) and FP174 strains (lanes 2 and 5), and from S. gordonii (lanes 3 and 6). A homogeneous mixture of 5 human sera (lanes 1–3) or affinity-purified anti-epiA antibodies (lanes 3–6) were used.
