Abstract

The present invention is related to compounds comprising mannitol or glucitol derivatives which may be used to build up oligomeric compounds. The invention is further related to uses of these oligomeric compounds for hybridization and as probes. In addition, methods for the detection of nucleic acids are disclosed wherein the oligomeric compounds are used.

Description

technical field [0001] The present invention relates to compounds comprising mannitol or sorbitol derivatives which can be used to form oligomeric compounds. The invention also relates to the use of these oligomeric compounds in hybridization and as probes. In addition, the present invention discloses methods for detecting nucleic acids in which oligomeric compounds are used. Background technique [0002] In the field of molecular diagnostics, detection of target nucleic acids by polymerase chain reaction (PCR) plays an important role. Routine screening of blood banks for human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV) is an example of the large-scale application of PCR-based diagnostic methods. Automated systems for PCR-based analysis often use real-time detection of amplification products during PCR. Key to this approach is the use of modified oligonucleotides that carry reporter groups or labels. [0003] In its simplest form, P...
