Primers and probe-binding sequence of the in-house B19 DNA assays. The reference sequences of three B19 virus genotypes are aligned. Primers sequences were underlined with solid lines, and probe sequence was underlined with dashed line. B19 Genotype 1 sequence M13178 is used as reference sequence. For B19 Genotype 2 and 3, the Lali strain [GenBank: AY044266] and V9 strain [GenBank: NC-004295] are included in this alignment
