The SeqStudio™ for human identification (HID) is a new benchtop capillary electrophoresis (CE) platform recently developed by Applied Biosystems for genotyping and sequencing short tandem repeat (STR) fragments. Compared to the previous series of CE systems developed by this maker, it is more compact and easier to use. Moreover, by allowing the detection of 4 to 8 fluorescent dyes, it seems to be fully compatible with the different kits of autosomal and gonosomal STR markers usually used in forensic genetics, which are available in trade and supplied by various manufacturers. However, being a new CE model, before its routine use in forensic genetics applications, it should undergo appropriate analytical validation studies in its own laboratories to understand its potential and limitations. A series of experiments on DNA samples coming from cell line controls, using the GlobalFiler™ IQC Amplification Kit, were carried out to meet this purpose. The SeqStudio™ Genetic Analyzer for HID's findings on genotyping reproducibility (precision and accuracy of sizing), sensitivity, signal variability between dyes (intra- and inter-color channel balance), and stutter ratios are reported. These findings confirm the validity of this new CE system and its capability to generate reliable results. [ABSTRACT FROM AUTHOR] |
