A universal probe system for low-abundance point mutation detection based on endonuclease IV.

Abstract excerpt

Single base mutations are closely related to cancer diagnosis and treatment. The fluorescent probe method is one of the important methods to detect single-base mutations. We constructed a universal probe detection system based on endonuclease IV and the DNA strand displacement reaction. The system uses two toehold strand displacement reactions to relay the mutation information to the universal strand. There is no...
