متن کاملThe fetal fraction of cell-free DNA in maternal plasma is not affected by a priori risk of fetal trisomy
OBJECTIVE To determine the relationship between a priori risk for fetal trisomy and the fraction of fetal cell-free DNA (cfDNA) in maternal blood. METHODS A comparative analysis on fetal cfDNA amounts was performed in subjects stratified into a priori risk groups based on maternal age, prenatal screening results, or nuchal translucency measurement. RESULTS Across the highest and lowest deci...

is more sensitive but requires two steps [two rounds of amplification (PCR LDR) are needed]. The costs for setup are larger (PCR primers and three labeled oligonucleotides are needed per SNP) with respect to PCR/RFLP and allele-specific PCR but are similar for the TaqMan assay. The main advantage consists in the inherent multiplexing capability that can increase throughput, which decreases cost...
متن کاملIntroducing a New and Simple Protocol for Capillary Electrophoresis of Cell Free Fetal Double Stranded DNA
Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...
متن کاملA NEW WORKFLOW OF FETAL DNA PREDICTION FROM CELL-FREE DNA IN MATERNAL PLASMA by
Prediction of fetal DNA allows diagnosing known/passed mutations before child’s birth. Public health significance of such early testing is that it can reassure parents who have negative results and offers timely information for those with abnormal results. My dissertation work presents a new approach of reconstructing fetal DNA from maternal plasma. The method works because plasma from pregnant...
