Zusammenfassung:Methods of reducing adapter-dimers in a sequencing library are provided according to aspects of the present disclosure, including: hybridizing excess 3' adapters to blocker oligonucleotides forming a hybridized complex, such that the excess 3' adapters are unavailable to form adapter-dimers, the hybridized complex including: a first blocker oligonucleotide 3' terminus adjacent to an adenylated nucleotide at the 5' terminus of a first unligated 3' adapter and a second blocker oligonucleotide 3' terminus adjacent to an adenylated nucleotide at the 5' terminus of a second unligated 3' adapter, wherein the first blocker oligonucleotide has a 5' portion complementary to and hybridized to the first unligated 3' adapter, the second blocker oligonucleotide has a 5' portion complementary to and hybridized to the second unligated 3' adapter, and the first blocker oligonucleotide has a 3' portion complementary to, and hybridized to, a 3' portion of the second blocker oligonucleotide. The first and second blocker oligonucleotides may be the same oligonucleotide comprising a palindromic sequence which allows for self-hybridisation.
