54 QIAxcel Advanced Application Guide 10/2016 Conclusions • The QIAxcel capillary electrophoresis system is highly suited for reproducibly detecting Y chromosome microdeletions and rearrangements in a fast and reliable manner. • Using the QIAxcel system with the QIAxcel DNA High Resolution Kit, Y chromosome microdeletions were detected by direct analysis of PCR products: prior manipulation of the samples was not necessary. • Results of this research, described in (4), facilitated the construction of a minimal set of markers to be used for detecting AZF microdeletions. The use of these markers will assist the research on the effect of AZF mutations on male fertility. References 1. Tiepolo, L., and Zuffardi, O.
