Summary: | Provided is a linker element and a method of using the linker element to construct a sequencing library, wherein the linker element consists of a linker A and a linker B, the linker A is obtained through the complementary pairing of a long nucleic acid strand and a short nucleic acid strand, the 5' end of the long strand has a phosphoric acid modification, and the 3' end of the short strand has an enclosed modification, with enzyme sites in the short strand; the linker B is a nucleic acid single strand, the 3' end thereof can be in a complementary pairing with the 5' end of the long strand of the linker A; and there are II type restriction endonuclease recognition sites in the long strand of the linker A and the linker B. Using the linker element of the present invention for constructing a sequencing library ensures the linking directionality of the linkers while solving the problems of fragment interlinking, linker self-linking and low linking efficiency, and reducing the purification reaction between steps, |
