摘要:
A process for detecting nucleic acids, having the following steps: providing at least one nanoparticle that is functionalised for the nucleic acid to be detected by means of at least one oligonucleotide that is bound to it and that is able to hybridize with at least one segment of a nucleic acid to be detected; bringing the functionalised nanoparticle into contact with a sample in which the nucleic acid is to be detected; and measuring a property that provides information about the degree of hybridization of the at least one oligonucleotide with the nucleic acid to be detected. In addition, the process includes the step of exciting the nanoparticles to generate heat, for example by means of a photothermal effect. The invention is suitable, in particular, for high-throughput DNA analysis.

The present invention is directed to hybridization probes hybridizing adjacently to another at a target nucleic acid sequence, wherein one member of said hybridization probes comprises (i) a nucleotide sequence entity which is substantially complementary to the sequence of the target nucleic acid, (ii) a fluorescent entity being either a FRET donor entity or a FRET acceptor entity, and (iii) a spacer entity connecting the nucleotide sequence entity and the fluorescent entity.
摘要:
The current invention restates substituted nitroindole nucleosides as both terminal as well as internal building blocks of labeled oligonucleotide probes for the detection, analysis and quantitation of nucleic acids. The substituent comprises a linker and a detectable group or a linker and a reactive group for post synthesis coupling. These modified nucleosides grant access to a wide application area. These new substituted nitroindole nucleosides can be used as labeling reagents for the facile preparation of, e.g., optimized hybridization probes, simple probes, TAQMAN-probes or molecular beacon probes.
