FIG. 4.
Detection of FtsZAna by immunoblotting. Purified FtsZAna produced from E. coli (lane 1) and protein lysate from Anabaena sp. strain PCC 7120 (lane 2) were immunodetected with a serum raised against the recombinant FtsZAna. Immunodetection was carried out as described elsewhere (30). Sizes are indicated in kilodaltons.
