Representative agarose gel electrophoreses of amplified HDV-products. a HDV specific nRT-PCRs showing results of the first PCR round (HDV-specific amplicon of 323 bp) and b nested PCR with an HDV-specific amplicon of 235 bp. Lanes 1-21 correspond to PCR results from serum samples. HDV-positive samples with correct size in (b) are denoted with the patient number, e.g., 14-445 (see (b) lane 13 and 21; upper lanes, and lane 4 and 10, lower lanes). PC is the HDV-positive control (acc. No. M21012, [27]); NC is the negative control. Lane M shows a 100 bp DNA ladder, base pairs (bp) of the marker are denoted at the left
