Q-PCR was performed on cDNA derived from in vitro bradyzoites of vector control strains VC1 (white bars) and VC2 (gray bars), TgRSC8 mutant C9 (black bars), and three complemented strains (comp1-3, patterned bars) to analyze transcript levels of bradyzoite-induced genes BAG1, LDH2 (panel A), SUSA1, ENO1 (panel B), a bradyzoite-induced HSP70, BRP1, BGR1 and SAG2X (panel C). Transcripts of constitutive genes GRA2 and GAPDH were also quantified (panel D). Transcript levels were expressed as a percentage of the level of housekeeping gene TUB1 per sample. Shown are the averages and standard deviations of three experiments, performed on cDNAs derived from independent RNA samples.
