This invention relates to a peptide nucleic acid (PNA) oligomer which is conjugated with one or more linear-type amino acid containing a plurality of alkyleneglycols and to a synthesis method thereof. In addition, this invention related to a linear amino acid spacer in a device for detection for detecting a target gene using the PNA oligomers which is fixed on a surface of a functionalized solid support. The linear amino acid spacer contains a plurality of alkyleneglycols and maintains enough space between the solid support and PNA oligomer in the device in order to prevent the interference of the interaction between the PNA oligomer and a target gene. Furthermore, this invention relates to a PNA array, a PNA chip and a gene diagnosis kit whereof sensitivity and specificity are improved by being manufactured with the PNA conjugated with the amino acid spacer.

Synthesis of peptide nucleic acids conjugated with amino acids and their application

The present invention relates to a peptide nucleic acid (PNA) conjugated with multi-amine linkers, and a method to prepare the same and utilization thereof. More specifically, the method is characterized by conjugating monomers having multi-amine functionality sequentially at a PNA terminal, and effectively immobilizing the PNA conjugated with multi-amine linkers on a solid surface. A PNA array prepared using the PNA conjugated with multi-amine linkers exhibits improved sensitivity and specificity of signals for detecting target nucleic acids as compared to a PNA array using PNA probes having only one amine group. The PNA conjugated with multi-amine linkers can be utilized in nucleic acid detecting devices or kits for gene diagnosis such as PNA microarrays, PNA chips, PNA field-effect transistors and impedance detectors.
