(A) The Southern blots indicating the presence of a single copy-gene. A probe ranging from 373-1911 bp of the coding sequence of the PRP1 gene hybridized of Sac II and Kpn I-digested genomic DNA to single bands as expected from the cDNA sequence. (B) The Northern blot shows that the gene is expressed. The PRP1 gene is expressed in both dividing (Div.) and isolated T. gondii tachyzoites (Iso), but not in the parasite host cells (HFF). The same probe as in (A) was used for the hybridization. The arrows and numbers indicate the size of the DNA fragments in kbp or kilo bases, respectively. |
