104 QIAxcel Advanced Application Guide 10/2016 The band at 204 bp was also present in lane 2 for S. scombrus, and in lane 4 for Salmo salar. The band at 273 bp appeared in lane 4 for S. salar, and finally, the band at 466 bp was visible in lane 3 for Merluccius merluccius. Table 3 compares sizes of the observed HinfI restriction fragments with the theoretically expected fragments. The deviation average between theoretical and observed data was 4 bp.
