摘要: Polymerase chain reaction (PCR)-based assays have become increasingly prevalent for sexing embryos. The aim of the present study was to develop a suitable duplex PCR procedure based on amplification porcine repetitive sequences tissues, embryos and single cells. Primers were designed targeting X12696 Y chromosome-specific repeat sequence (SUSYa SUSYb; sex-related primer sets), multicopy porcine-specific mitochondrial 12S rRNA gene (SUS12S; control set) X51555 1 chromosome (SUS1; set). specificity sets established technique optimised by testing combinations two specific (SUSYa/SUS12S; SUSYb/SUS12S), different concentrations, sources DNA polymerase, melting temperatures numbers cycles using genomic from ovarian testicular tissue. SUSYa/SUS12S- SUSYb/SUS12S-based procedures applied in vitro-produced (IVP) blastocysts, cell-stage oocytes. SUSYb/SUS12S primer-based successfully sexed cells IVP (100% efficiency), as well blastocysts (96.6% accuracy; 96.7% efficiency). This is first report demonstrate applicability these this purpose. In conclusion, highly reliable sensitive
