    • Methodologies for determining the presence of specific nucleic acid sequences in a sample of eucaryotic origin using in situ hybridization are described. The in situ hybridization is performed using a hybridization solution comprising at least one binding partner capable of hybridizing to the specific nucleic acid sequence to be determined so as to form hybrids and a hybrid destabilizing agent in an amount effective to decrease the melting temperature of hybrids formed between the nucleic acid and the binding partner so as to increase the specific binding and decrease the non-specific binding. The binding partner used is a polymeric strand of polymerized moieties having a non-cyclic backbone, the polymeric strand being capable of hybridizing to the nucleic acid sequence to be determined. The method is particularly suitable for diagnosing different human diseases such as bacterial and viral infections, genetic diseases and neoplastic disorders.
    • 描述了使用原位杂交确定真核来源样品中特定核酸序列的存在的方法。 原位杂交使用包含至少一个结合配偶体的杂交溶液进行,所述结合配偶体能够与需要测定的特异性核酸序列杂交以形成混合物和混合去稳定剂,其量有效降低形成的杂交体的熔解温度 在核酸和结合配偶体之间,以增加特异性结合并降低非特异性结合。 使用的结合配偶体是具有非环状主链的聚合部分的聚合物链,所述聚合物链能够与待确定的核酸序列杂交。 该方法特别适用于诊断不同的人类疾病,如细菌和病毒感染,遗传疾病和肿瘤性疾病。

    • This invention relates to antibodies to complexes formed between PNA (Peptide Nucleic Acid) and nucleic acids, particularly antibodies to PNA/DNA or PNA/RNA complexes. The preferred antibodies are polyclonal, monoclonal and recombinant antibodies that binds to PNA/DNA or PNA/RNA complexes, but not to single-stranded PNA, double-stranded nucleic acid or single-stranded nucleic acid. Peptide Nucleic Acids (PNA) are newly developed, not naturally occurring compounds comprising a polyamide backbone bearing a plurality of ligands such as naturally occuring nucleobases attached to a polyamide backbone through a suitable linker. PNA oligomers with a backbone of N-(2-aminoethyl)glycin units have a surprising high affinity for complementary nucleic acid forming very stable and specific complexes. This property makes PNA oligomers suitable as hybridization probes for detection of nucleic acids. The usability of PNA as hybridization probes is greatly increased by the present antibodies. The antibodies according to the invention are useful in the capture, recognition, detection, identification or quantitation of nucleic acids in biological samples, via their ability to react with PNA-nucleic acid complexes.
    • 本发明涉及在PNA(肽核酸)和核酸之间形成的复合物的抗体,特别是针对PNA / DNA或PNA / RNA复合物的抗体。 优选的抗体是结合PNA / DNA或PNA / RNA复合物但不与单链PNA,双链核酸或单链核酸结合的多克隆,单克隆和重组抗体。 肽核酸(PNA)是新开发的,而不是天然存在的化合物,其包含具有多个配体的聚酰胺主链,例如通过合适的接头天然存在连接到聚酰胺主链的核碱基。 具有N-(2-氨基乙基)甘氨酸单元骨架的PNA寡聚体对形成非常稳定和特异性复合物的互补核酸具有惊人的高亲和力。 该性质使得PNA低聚物适合作为检测核酸的杂交探针。 通过本发明的抗体,PNA作为杂交探针的可用性大大提高。 根据本发明的抗体可用于通过其与PNA-核酸复合物反应的能力捕获,识别,鉴定或定量生物样品中的核酸。
