Method for selectively detecting subsets of nucleic acid molecules

摘要

Method for selectively detecting nucleic acid molecules comprising structural aberrations that are capable of being convented into nicks comprising generating linear nucleic acids from a selected nucleic acid substrate population; denaturing and re-annealing the linear nucleic acids to form nucleic acid duplexes; masking the nucleic acid duplex termini and internal structural aberrations with a masking component; modifying the masked nucleic acids by introducing nicks therein using at least an enzyme possessing endonuclease activity: labelling the modified nucleic acids with labelled nucleotides via nucleic acid nick translation with at least an enzyme displaying a nucleic acid polymerase activity; and selecting and identifying the labelled nucleic acid.
