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.
本发明涉及一种与一种或多种含有多个烷基二醇的线性
氨基酸共轭的肽核酸(
PNA)寡聚体及其合成方法。此外,本发明涉及一种线性
氨基酸间隔物,其用于检测装置中,用于检测靶
基因的
PNA寡聚体固定在功能化固体支持物的表面上。线性
氨基酸间隔物包含多个烷基二醇,并在装置中保持固体支持物和
PNA寡聚体之间足够的间隔,以防止
PNA寡聚体与靶
基因之间的相互作用干扰。此外,本发明涉及一种
PNA阵列、
PNA芯片和
基因诊断试剂盒,其灵敏度和特异性得到提高,因为它们是用与
氨基酸间隔物共轭的
PNA制造的。
