Web11 Apr 2024 · Homemade two-person DNA mixtures were used to simulate a mixture of cell-free fetal DNA and maternal DNA in the mother’s peripheral blood plasma. Of the four allele-specific primers, three could successfully amplify minor component alleles from a 1:500 mixture without being affected by the major component alleles, while the other primer … WebToward the end of the 1990s a new approach emerged that simply looked in the maternal circulation for free floating, or “cell-free,” fragments of circulating DNA from the fetus, rather than searching for intact fetal cells. 4 Early work showed that these fetal DNA fragments were not only abundant, but could be differentiated from circulating maternal DNA …
