  • Primer for nucleic acid random fragmentation and nucleic acid random fragmentation method
    Patent number: 10563196
    Abstract: The present invention provides a primer for nucleic acid random fragmentation and a nucleic acid random fragmentation method. The primer consists of a plurality of upstream random primers and downstream random primers. The sequence composition of the upstream random primers is 5?-X-Y-3?, and the sequence composition of the downstream random primers is 5?-P-Y?-X?-close-3?, wherein Y and Y? are random sequences, X is all or part of sequences of a sequencing platform 5? end adaptor, X? is all or part of sequences of a sequencing platform 3? end adaptor, P is phosphorylation modification, and close is close modification. The primer of the present invention adopts double random anchoring of both the upstream random primers and the downstream random primers, and a DNA sample can be randomly broken.
