Patent ID: 11739319

Abstract:
Provided are a PCR primer pair and an application thereof. The PCR primer pair comprises: a first primer and a second primer, wherein the first primer comprises a first specific sequence and a first random sequence; the first specific sequence is located on end 3′ of the first primer, and the first random sequence is located on end 5′ of the first primer; the second primer comprises a second specific sequence and a second random sequence, the second specific sequence is located on end 3′ of the second primer, and the second random sequence is located on end 5′ of the second primer; moreover, the first specific sequence and the second specific sequence are an upstream primer and a downstream primer directed to a target sequence, respectively; the first random sequence and the second random sequence are reverse complementary; a predetermined restriction enzyme cutting site is connected between the first specific sequence and the first random sequence; and a predetermined restriction enzyme cutting site is connected between the second specific sequence and the second random sequence.
