Embodiment

[0123] Example: The detection of fetal chromosome triploid variation was performed on the blood plasma of 36 pregnant women.

[0124] 1. Sample collection and processing:

[0125] (1) Take 2ml of maternal peripheral blood during pregnancy, centrifuge at 1600g, 4°C for 10 minutes, separate blood cells and plasma, and then centrifuge the plasma at 16000g, 4°C for 10 minutes to further remove residual white blood cells. SnoMag for Maternal Plasma TM CirculatingDNAKit (SNOVA) was used to extract plasma DNA, and finally the DNA was dissolved in 50ulTE solution.

[0126] 2. Construction of sequencing library

[0127] 2.1 rSAP processing

[0128] Use the following reaction system for rSAP treatment for dephosphorylation

[0129] DNA50ul

[0130] rSAP(1U / ul)6ul

[0131] 10XNEBuffer26ul

[0132] After mixing, put it on the PCR machine for reaction, the program is: 37°C / 45min, 65°C / 10min, 0.1°C / s uniform cooling to 4°C.

[0133] 2.2 End Repair

[0134] The reaction is carried o...
