Expression profile analyses of cir genes in different tissues of infected mice by RT-PCR RFLP. For RFLP analyses, organs and blood were collected at a parasitaemia of 30% from female NMRI mice infected with 100 pRBCs. After RT-PCR amplification for the six host tissues with the subfamily-specific primers, 150 ng of purified RT-PCR products (approx. 600 bp) were digested with Alu I. The DNA fragments (30 ng) were analysed using the DNA 1000 kit for the Agilent 2100 bioanalyzer for accurate sizing. Compared are RT-PCR RFLP profiles of blood, liver, spleen, kidney, lung and brain for four mice for cir subfamily 1 (A) and cir subfamily 2 (B). DNA 1000 bp ladder was used and in each lane an upper (1000 bp, purple) and a lower (25 bp, green) marker are indicated.
