Abstract:

Ribonuclease(RNase) H-dependent polymerase chain reaction(PCR)(rhPCR) adds RNase H2 and blocked cleavable rhPCR primers based on PCR,which eliminates the formation of primer-dimers in the reaction process,greatly reduces the occurrence of error amplification,and significantly improves the specificity,sensitivity and repeatability of the reaction. The rhPCR shows certain advantages in single nucleotide polymorphism(SNP),genotyping,multi-target simultaneous detection,environmental nucleic acid detection and so on. This review summarizes the background,principles,key technology,technical advantages,application and development prospects of rhPCR.

Key words: Ribonuclease H-dependent polymerase chain reaction, Blocked cleavable primer, Ribonuclease H2
