QIAxcel Advanced Application Guide 10/2016 75 was used to estimate the size of the PCR amplicons. Sizing was done automatically using the QIAxcel ScreenGel® software. Allele calling was performed automatically using a peak calling table that defines the size of the alleles according to theoretical tables (2) and a tolerance in % for each locus to exclude any overlapping data. Then the results were merged into an Excel® spreadsheet and submitted to the free online genotyping database. Reference sizing method Sanger sequencing was used as a reference method to determine the amplicon sizes. Table 1.
