Abstract
The disclosure relates to a method for constructing a plasma Deoxyribonucleic acid (DNA) sequencing library. The method includes: extracting a plasma DNA; making the plasma DNA ligate to a sequencing linker, and purifying a ligation product; performing Polymerase Chain Reaction (PCR) amplification for the purified ligation product, purifying the PCR amplification product, and obtaining the plasma DNA sequencing library, wherein, the method does not include the step of performing 5′-terminus phosphorylation for the plasma DNA. The kit provided by the disclosure includes: a reagent which ligates a plasma DNA to a sequencing linker, including the sequencing linker, a ligase and a ligation buffer; and reagents and instruments for purifying the ligation product; a reagent which performs PCR amplification for a purified ligation product, and reagents and instruments for purifying the PCR amplification product; wherein, the kit does not include the reagent which performs 5′-terminus phosphorylation for the plasma DNA.
