Abstract: Provided are a PCR primer pair and an application thereof. The PCR primer pair comprises a first primer and a second primer, wherein the first primer comprises a first specific sequence, a first random sequence, and a first universal sequence, the first specific sequence is located at the 3′ end of the first primer, the first random sequence is located at the 5′ end of the first primer, and the first universal sequence is located between the first specific sequence and the first random sequence; the second primer comprises a second specific sequence, a second random sequence, and a second universal sequence, the second specific sequence is located at the 3′ end of the second primer, the second random sequence is located at the 5′ end of the second primer, and the second universal sequence is located between the second specific sequence and the second random sequence, wherein the first random sequence and the second random sequence are inversely complementary.

Abstract: Provided is a method for isolating exosomal DNA, the method comprising: (i) providing a sample, wherein the sample comprises a blood sample from peripheral blood of a pregnant woman; and (ii) subjecting the sample to isolating, thus obtaining the exosomal DNA. Also provided are a method for detecting a blood sample, a method for constructing a sequencing library on a blood sample, a method for high-throughput sequencing an exosomal DNA sequencing library, a method for non-invasive prenatal gene detection, a device for non-invasive prenatal gene detection, and a kit for detecting a blood sample and use thereof.
