Transcriptional changes of cir gene expression during the course of infection. For RFLP analyses of expression changes of the cir genes during the course of infection, blood of female NMRI mice infected with 100 pRBCs were passaged on days 7, 14 and 21 days post infections (d.p.i.) into naïve female NMRI mice. Blood of these passaged mice was again collected at 30% parasitaemia. After amplification using the subfamily-specific primers for both subfamilies, 150 ng of purified RT-PCR products (approx. 600 bp) were digested with Alu I and 30 ng were then analysed using the DNA 1000 kit for the Agilent 2100 bioanalyzer. The RT-PCR RFLP profiles for four mice of subfamily 1 are presented in (A). The restriction digest of subfamily 2 are shown in the upper panel of (B) where only at day 7 p.i. and day 14 p.i. of mouse 1 a few smaller restriction fragments could be detected. Therefore a second digest with Xap I for 3 h at 37°C was performed (B, lower panel). DNA 1000 bp ladder was used and in each lane an upper (1000 bp, purple) and a lower (25 bp, green) marker are indicated.
