| Abstract: | LGC has developed a method for analysing low-level DNA samples called DNA SenCE (Sensitive Capillary Electrophoresis) based on post-PCR treatment of standard 28-cycle SGMplus PCR product and demonstrated to be equally effective at enhancing profiles as 34-cycle PCR. The method has been validated and accredited and used in casework since July 2007. Inherent in the method is the initial generation of a standard 28-cycle SGMplus profile so a direct comparison of standard and DNA SenCE results for all casework is possible. Here we review DNA SenCE casework, reporting the magnitude of peak enhancement and stochastic effects seen in the DNA SenCE profiles. |
