Optimized Real-Time Quantitative PCR Measurement of Male Fetal DNA in Maternal Plasma
15 Jul 2005
Abstract excerpt
BACKGROUND: Circulating fetal DNA (cfDNA) in maternal plasma has been measured to investigate its possible relationship with pregnancy-related disorders, including fetal trisomy 21 and preeclampsia. The circulating concentrations of single-copy fetal genes, however, are close to the detection limits of PCR methods. METHODS: We optimized a protocol for the real-time quantitative PCR amplification of the multicopy...
