Patent attributes
Provided is a nucleic acid isothermal self-amplification method comprising, adding suitable palindrome complementary sequences at both ends of a target template to form a stem-loop structure spontaneously, and providing reagents and conditions as needed to perform self-amplification. The method does not require addition of additional amplification primers. The reagent comprises a DNA polymerase having a strand displacement activity. The method does not rely on exogenous amplification primers for amplification, has a constant amplification temperature without a complex temperature control equipment, and achieves rapid amplification. The amplification product is a long single-stranded DNA of a continuous complementary sequence and can be applied to special occasions. In addition, the amplification has no GC bias.
