Disclosed are a process for increasing efficiency or specificity of hybridization between peptide nucleic acid (PNA) probes immobilized on a support and target nucleic acids, which comprises the step of fragment the target nucleic acids to reduce the size of the target nucleic acids, or selectively degrading the target nucleic acids which mismatch with the PNA probes, in the hybridization reaction between the PNA probes supported on a support and the target nucleic acids; and a composition and a kit therefor. |
