FIG. 1.
Representation of PCRan1 and PCMei2 within Pneumocystis DNA. (A and B) Southern blotting of PCRan1 (A) and PCMei2 (B) using, in lanes 1 to 6, respectively, rat DNA, uncut P. carinii genomic DNA, and EcoRI, HindIII, XhoI, and XbaI restriction enzyme-digested P. carinii genomic DNA. (C and D) Hybridization of PCRan1 (C) and PCMei2 (D) to P. carinii chromosomes separated by CHEF. Each lane contains P. carinii chromosomes derived from a single rat lung sample.
