SYNTHESIS OF PEPTIDE NUCLEIC ACIDS CONJUGATED WITH AMINO ACIDS AND THEIR APPLICATION

摘要

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 relates to a linear amino acid spacer in a device for detecting a target gene using the PNA oligomer 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.
